Reaktionsschritte
98.6 g of 2-aminobenzophenone were dissolved in a mixture of 650 ml of dichloromethane and 50 ml of water. A solution of 116.1 g of bromoacetyl bromide in 150 ml of dichloromethane was added dropwise to this mixture at a temperature of -10° C. The reaction mixture was then stirred at room temperature for a further 2 hours. The reaction mixture was worked up by adding water, separating the organic phase, washing again with water, drying and evaporating under reduced pressure. The crude product remaining as a residue was crystallized from ether/petroleum ether. 142 g of 2-[(2-bromoacetyl)-amino]-benzophenone having a melting point of 96-98° C. were obtained.
