Reaction Steps

To a solution of niacin (1.35 g, 11.0 mmol) in DCM (20 mL) were added N-methyl morpholine (3.34 g, 33.00 mmol) EDCI.HCl (4.2 g, 22.02 mmol), and L-leucinemethyl ester hydrochloride (2.0 g, 11.0 mmol). The mixture was allowed to stir at room temperature (25° C.) over 2.5 h under nitrogen atmosphere. The resulting mixture was diluted with DCM (200 mL), washed with water (3×100 mL) and dried over sodium sulphate. The crude product obtained upon evaporation of the solvent was further purified by silica gel column chromatography to obtain required product as white solid (2.0 g, 72%).
