Participants

Reaction Steps

A solution of Et3N (13.4 mL, 96.78 mmol) in CH2Cl2 (40 mL) was added to a solution of L-serine methyl ester hydrochloride (5.0 g, 32.26 mmol) and Ph3CCl (13.5 g, 48.39 mmol) in CH2Cl2 (129 mL) at 0° C. under N2 atmosphere. The reaction was then allowed to warm to room temperature and was stirred overnight. The reaction was quenched with saturated NaHCO3, the aqueous layer was extracted with CH2Cl2, and the combined organic layers were washed with brine, dried and concentrated, the residue was purified by silica gel column chromatography which gave the title compound as a colourless solid (11.41 g, 98%).
