PROCEDURE

实验过程

Iodomethane (554 mg) was added to a suspension of (S)-2-(benzyloxycarbonylamino)-3-(tert-butoxycarbonylamino)propionoic acid (1.1 g) and potassium carbonate (539 mg) in N,N-dimethylformamide (7 mL). The mixture was stirred for 2 hours at ambient temperature and partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over magnesium sulfate and concentrated in vacuo to give methyl (S)-2-(benzyloxycarbonylamino)-3-(tert-butoxycarbonylamino)propionate (1.2 g) as an oil.
