実験手順

A solution of bromoacetyl bromide (100 mL, 1.15 mol, Aldrich) dissolved in dichloromethane (300 mL) was added over 30 min to a solution of 2-aminobenzophenone (197 g, 1.0 mol, Fluka) dissolved in dichloromethane (1.3 L) and water (100) mL) cooled to -10° C. under vigorous mechanical stirring. The resulting mixture was stirred for an additional 1 h at -5° C. and then was allowed to warm to ambient temperature. The layers were separated, and the organic extract was washed with dilute sodium bicarbonate, then was dried over sodium sulfate. Evaporation afforded 309.8 g (95%) of 2-bromoacetamidobenzophenone as off-white crystals.
