실험 절차

Methyl 2-amino-3-hydroxypropanoate hydrochloride (L-serine methyl ester hydrochloride, 1.71 g, 11 mmol) was stirred in dichloromethane (20 ml) at 0° C., and triethylamine (2.79 ml, 20 mmol) added, followed by dropwise addition of 4-trifluoromethylbenzoyl chloride (1.486 ml, 11 mmol). The mixture was stirred at 0° C. for 30 minutes, then partitioned between dichloromethane and water, dried over magnesium sulfate, and filtered. Solvent was removed from the filtrate under reduced pressure, and the residue was purified by column chromatography, to yield methyl 3-hydroxy-2-{[4-(trifluoromethyl)phenyl]carbonylamino}propanoate, a compound of formula (13). B. Preparation of a Compound of Formula (14)
