실험 절차

Imidazole (20.4 g, 300 mmol) is added to a solution of homoserine (11.9 g, 100 mmol) in DMF (100 mL) and the solution is stirred 15 minutes then cooled to 0° C. tert-Butyldimethylsilyl chloride (13.7 g, 91 mmol) added and the mixture is stirred for ten minutes at 0° C. the for 4 hours at room temperature. The reaction mixture is poured into water (3 L) and the resulting solid is collected by filtration. The isolated product is dried and used without further purification.
