実験手順

To acetic anhydride (20.6 ml) was added formic acid (16.6 ml) at 15° C. The mixture was stirred at room temperature for 30 minutes. To the mixture was 2-(2-aminothiazol-4-yl)-2-(Z)-(acetoxyimino)acetic acid (10 g) under ice-cooling, and the reaction mixture was stirred at room temperature for 20 hours. To the mixture was added isopropyl ether (37.2 ml) under ice-cooling, and the mixture was stirred at the same temperature for 1 hour. The resulting precipitate was collected by filtration to give 2-(2-formylaminothiazol-4-yl)-2-(Z)-(acetoxyimino)acetic acid (9.39 g).
