Reaction Steps

4-Bromo-N-(4-chloro-phenyl)-benzamide (3) used is prepared by the following procedure. To a solution of 4-chloroaniline (1, 66.0 g, 517.4 mmol) and 4-bromobenzoyl chloride (2, 109.0 g, 497.5 mmol) in dichloromethane (1200 mL) is added triethyl amine (83.2 mL, 597.0 mmol). The reaction mixture is then poured into 0.05 N sodium hydroxide solution and the resulted suspension is stirred at rt for 1 h. The solid formed is filtered and washed well with water. It is dried in vacuo and used for the next step.
