Participants

Reaction Steps

HATU (494 mg, 1.3 mmol) was added via spatula to a solution of N-[5-benzyl-2-(ethoxycarbonyl)pyridin-3-yl]glycine (328 mg, 1.04 mmol), morpholine (0.113 mL, 1.3 mmol) and Et3N (0.18 mL, 1.3 mmol) in DMF (6 mL). After stirring for 45 min at rt, the solvent was removed in vacuo and the resulting material was dissolved in CH2Cl2 and washed with water. The organic layer was dried and concentrated. Purification of the crude material by silica gel chromatography eluting with 0-5% MeOH/CH2Cl2 afforded the product: 1H NMR (CDCl3) δ 8.57 (1H, br), 7.94 (1H, s), 7.23 (3H, m), 7.15 (2H, m), 6.68 (1H, s), 4.46 (2H, q, J=7 Hz), 3.95 (2H, s), 3.90 (2H, d, J=4.2 Hz), 3.68 (6H, br), 3.43 (2H, br), 1.42 (3H, t, J=7 Hz); ES+ MS: 384 (M+H+, 70).
