Reaktionsschritte

To a solution of 2-chloro-4-(chlorosulfonyl)benzoyl chloride (J. Org. Chem., 56,16, 1991, 4974) (300 mg, 0.877 mmol, 1 eq) in DCM (3 ml) was added 3-chloro-4-(trifluoromethyl)benzylamine (175 mg, 0.835 mmol, 0.95 eq) and Et3N (33 mg, 0.32 mmol, 0.37 eq) and the reaction mixture stirred at room temperature for 1 hour. The reaction mixture was diluted with ethyl acetate (10 ml), washed with water (10 ml), dried over sodium sulphate, filtered and evaporated. The crude material was purified by column chromatography eluting with ethyl acetate to yield the title compound (154 mg, 0.34 mmol, 39%).
