To a solution of Eugenol (0.3 g, 1.82 mmol) in DCM (20 mL), was added Boc-glycine (0.35 g, 2.01 mmol), N-methyl morpholine (0.65 mL, 6.00 mmol), EDC.HCl (0.76 g, 4.0 mmol) and DMAP at ice temperature. The mixture was allowed to stir at room temperature (25° C.) over a period of 12 h. The resulting mixture was diluted with DCM (100 mL), washed with water (2×50 mL) and dried over sodium sulphate. The crude product obtained upon evaporation of the solvent was purified by silica gel column chromatography to obtain resulting product as pale yellow oil (300 mg, 46.9%)
