실험 절차

To a solution of methyl [1-(3-methoxyphenyl)-2-[(methylamino)carbonyl]hydrazino]acetate (1.6 g) in methanol (20 ml) under nitrogen was added a solution of sodium methoxide (8 ml; from sodium (5.2 g) in methanol (150 ml)). After 1 h the mixture was poured into pH 6 phosphate buffer (100 ml) and partitioned with dichloromethane (3×50 ml). The combined, dried organic extracts were evaporated to give a solid which was purified by FCC eluting with System A (7:3) to give, after trituration with System A (1:1), the title compound (650 mg), m.p. 120°-122°.
