Procedure

Cyclohexylamine (9.111 g) was dissolved in tetrahydrofuran (100 ml), followed by the addition of 4-bromobenzoyl chloride (5.04 g)/tetrahydrofuran solution (30 ml) under ice-cooling, and the mixture was stirred for 20 min. The reaction mixture was partitioned between ethyl acetate and water. The resulting organic layer was washed with water, dried (over MgSO4) and evaporated. The resulting residue was recrystallized from ethyl acetate/hexane, to give the title compound as a pale pink solid (5.236 g, yield; 83%).
