YieldReaction ConditionsOperation in experiment
With 4-methyl-morpholine; thionyl chloride; In dichloromethane; N,N-dimethyl-formamide; Step A N-(BOC)-4-((3',5'-dichloroisonicotinoyl)amino)-(L)-phenylalanine, methyl ester A slurry of <strong>[13958-93-5]3,5-dichloroisonicotinic acid</strong> (3.1 g, 16.11 mmol) in 10 mL of CH2Cl2 was treated with DMF (50 muL) and thionyl chloride (1.23 mL, 16.91 mmol) and heated to reflux for 5 h. The reaction was concentrated to give a yellow oil. This oil was dissolved in 5 mL of CH2Cl2 and added to N-(BOC)-4-amino-(L)-phenylalanine, methyl ester (4.00 g, 14.39 mmol) and 4-methylmorpholine (2.7 mL, 24.21 mmol) in 25 mL of CH2Cl2 at 0 C. After stirring for 2 h at this temperature, the reaction was quenched with water (50 mL) and extracted into CH2Cl2 (3*100 mL). The combined organics were combined, dried over anhydrous MgSO4 and concentrated in vacuo to give a yellow solid. Trituration with CH2Cl2 gave 5.5 g of a while solid 1H NMR (500 MHz, CDCl3): delta 8.63 (s, 2H); 7.58 (d, J=8.2 Hz, 2H); 7.23 (d, J=8.2 Hz, 2H); 6.91 (d, J=8.4 Hz, 1H); 4.39 (m, 1H); 3.70 (s, 3H); 3.11 (m, 1H); 2.91 (m, 1H); 2.00 (s, 9H); MS m/e 468.20 (M+).
