Procedure

1.50 g (6.27 mmol) of N-[(benzyloxy)carbonyl]-(DL)-serine was dissolved in 10 ml of N,N-dimethylformamide. 885 mg (13.2 mmol) of imidazole and 1.98 g (13.2 mmol) of t-butyldimethylchlorosilane were added to the obtained solution at 0° C., and they were stirred overnight. Water was added to the reaction mixture and they were stirred for 10 minutes. After extracting with ethyl acetate 3 times followed by the drying over anhydrous sodium sulfate, the solvent was evaporated under reduced pressure to obtain the title compound.
