실험 절차

A solution of 1,3-bis(N-tert-butoxycarbonyl-L-valyloxy)-2-propyl 1-iodoethyl carbonate (0.156 mmol) and cefotaxime sodium (67.8 mg, 0.142 mmol) in 3.2 mL dry N,N′-dimethylformamide was stirred under argon for 22 h. The reaction mixture was concentrated and subjected to column chromatography (silica, 2/1 petroleum ether—ethyl acetate, and then 20/1 CH2Cl2-methanol) to yield an oil enriched in the desired product. The oil was dissolved in 10 mL ethyl acetate, washed with water, dried, and concentrated. A second chromatography (silica, 40/1 CH2Cl2-methanol) gave the title compound (59.7 mg) as cream-colored solids.
