YieldReaction ConditionsOperation in experiment
30% Example 104 4-(3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)quinazoline To a solution of a hydroxyquinazoline (400 mg, 2.73 mmol), and BOP (1450 mg, 3.2 mmol) was added DBU (0.61 mL, 4.09 mmol) at room temperature under nitrogen. The resultant mixture was stirred for 5-10 min at room temperature, after which 3H-[1,2,3 <strong>[273-34-7]triazolo[4,5-b]pyridine</strong> (714 mg, 6.0 mmol) was added. The reaction mixture was monitored by LCMS till complete consumption of starting material (30 hrs). The solvent was removed under vacuum, the crude reaction mixture was purified by a flash chromatography on SiO2 column eluted with hexanes/EtOAc to give the desired product (200 mg, 30%). 1H-NMR (CDCl3, 400 MHz) delta (ppm) 9.43 (s, 1H), 9.01 (d, 1H, J=8.4 Hz), 8.93 (m, 2H), 8.22-8.19 (m, 2H), 7.99-7.96 (m, 1H), 7.87 (dd, 1H, J=8.0 Hz, J=4.4 Hz).

YieldReaction ConditionsOperation in experiment
With di-isopropyl azodicarboxylate; triphenylphosphine; In tetrahydrofuran; at 0 - 20℃; To a stirred solution of compound 1C (30 mg, 0.12 mmol) in anhydrous THF (3.0 mL) were sequentially added compound ID (28 mg, 0.23 mmol) and triphenyl phosphine (61 mg, 0.23 mmol). The reaction mixture was cooled to 00C, and to it diisopropyl-azodicarboxylate (0.05 mL, 0.23 mmol) was added in drop wise manner. After the addition was over, stirring continued for another 0.5 h at 00C and then for 12 h at room temperature. Solvents were removed in vacuum and the residue was purified by preparative HPLC to provide compounds 1 and 2 as TFA salts. ESI-MS for both compounds:m/z 362.1 (M+H)+.
