YieldReaction ConditionsOperation in experiment
With ammonium hydroxide; caesium carbonate; In ethyl acetate; toluene; Part B. Soluble copper(I)-catalyzed Ullmann coupling reaction. A suspension of 1-(4-iodo-phenyl)-3-morpholin-4-yl-5,6-dihydro-1H-pyridin-2-one (10, 2.2 g, 5.73 mmol), piperidin-2-one (42, 851 mg, 8.59 mmol, 1.5 equiv), and Cs2CO3 (3.73 g, 11.46 mmol, 2.0 equiv) in toluene (15 mL) was treated with Cu(PPh3)3Br (1.065 g, 1.146 mmol, 20% equiv) at room temperature under N2, and the resulting reaction mixture was degassed three times under a steady stream of nitrogen. The reaction mixture was warmed up to reflux for 6 h. When HPLC showed the Ullmann coupling reaction was complete, the reaction mixture was cooled down to 5-10 C. before being quenched with 14% of ammonium hydroxide aqueous solution (20 mL) and EtOAc (30 mL) at 5-10 C. The mixture was stirred for an additional 4 h at 25 C. The two layers were then separated, and the aqueous layer, was extracted with EtOAc (3*20 mL). The combined organic extracts were washed with saturated NaCl aqueous solution (10 mL), dried over MgSO4, and concentrated in vacuo. The residue was directly purified by flash column chromatography (SiO2, 15-40% EtOAc/hexane gradient elution) to afford the desired 3-morpholin-4-yl-1-[4-(2-oxo-piperidin-1-yl)-phenyl]-5,6-dihydro-1H-pyridin-2-one (63, 1.568 g, 2.036 g theoretical, 77%) as a pale-yellow oil, which solidified upon standing at room temperature in vacuo. For 63, CIMS m/z 356 (M++H, C2OH25N3O3).

With hydrogenchloride; triethylamine; In ethyl acetate; Example 55 1-(4-Methoxy-phenyl)-7-oxo-6-[4-(2-oxo-piperidin-1-yl)-phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylic acid ethyl ester (65). A solution of chloro[(4-methoxyphenyl)hydrazono]acetic acid ethyl ester (34, 470 mg, 1.3 mmol) in EtOAc (4 mL) was treated with 3-morpholin-4-yl-1-[4-(2-oxo-piperidin-1-yl)-phenyl]-5,6-dihydro-1H-pyridin-2-one (63, 334 mg, 1.3 mmol, 1.0 equiv) at 0-5 C. under N2, and the resulting reaction mixture was treated with triethylamine (TEA, 263 mg, 0.33 mL, 2.6 mmol, 2.0 equiv) at 0-5 C. under N2. The reaction mixture was then warmed up to room temperature for 30 min before being warmed up to reflux for an additional 6 h. When HPLC and TLC showed that the reaction was complete, the reaction mixture was cooled down to 5-10 C. before being treated dropwise with a 4.0 N aqueous HCl solution (1.7 mL, 6.5 mmol, 5.0 equiv) at 0-5 C. The resulting mixture was stirred at 5-20 C. for 4 h. The resulting slurry was then treated with water (10 mL) and EtOAc (10 mL) before the two layers were separated. The aqueous layer was extracted with EtOAc (2*10 mL). The combined organic extracts were washed with saturated NaCl aqueous solution (5 mL), dried over MgSO4, and concentrated in vacuo. The residue was directly purified by flash column chromatography (SiO2, 15-40% EtOAc/hexane gradient elution) to afford the desired 1-(4-methoxy-phenyl)-7-oxo-6-[4-(2-oxo-piperidin-1-yl)-phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylic acid ethyl ester (65, 423 mg, 635 mg theoretical, 67% for two steps) as pale-yellow solids, which solidified upon standing in vacuo at room temperature. For 65, CIMS m/z 489 (M++H, C27H28N4O5).

YieldReaction ConditionsOperation in experiment
84.5% With sodium hydride; In tetrahydrofuran; at 10 - 25℃;Inert atmosphere; The 1f (12.8g, 32.7mmol) was dissolved in tetrahydrofuran (250ml) in an ice bath was added portionwise sodium hydride (1.73g, 72.1mmol) to obtain a reaction mixture, said reaction mixture at room temperature overnight. Tracking progress of the reaction by TLC, the reaction was completed, the reaction mixture was added to ice water and quenched with sodium hydride, tetrahydrofuran was removed by distillation under reduced pressure, dichloromethane was added and extracted two times the combined organic phases were dried over anhydrous magnesium sulfate, filtered, after the solvent was distilled off under reduced pressure, the residue was purified by column chromatography to give 1g (9.8g, yellow solid), yield: 84.5%;
