실험 절차

A mixture of 2-t-butoxycarbonylmethoxyimino-2-(2-formamidothiazol-4-yl)acetic acid (syn isomer) (15.0 g) and conc. hydrochloric acid (9.5 g) in methanol (75 ml) was stirred at ambient temperature for 2.5 hours. Water (100 ml) was added to the reaction mixture and the solution was adjusted to pH 3.0 with 10% aqueous solution of sodium hydroxide under stirring. The precipitates were collected by filtration, washed with water and diisopropyl ether and dried to give 2-t-butoxycarbonylmethoxyimino-2-(2-aminothiazol-4-yl) acetic acid (syn isomer) (12.7 g).
