実験手順

To a solution of (Z)-2-(2-aminothiazol-4-yl)-2-(triphenylmethoxyimino)acetic acid (5.81 g, 13.47 mmol) in DMF (30 mL) at room temperature (1 mL) was added N-chlorosuccinimide (1.80 g, 13.47 mmol). After overnight reaction the reaction mixture was poured into water (about 500 mL) and the resulting precipitate was filtered, washed with water and then with ethyl acetate and dried in vacuum to afford 4.43 g (71%) of the title compound. 13C NMR (CDCl3) δ 108.5, 125.6, 126.2, 126.6, 12.3, 134.7, 141.8, 146.5, 162.1, 163.3.
