Reaction Steps

2-Amino-5-benzyloxy-N,N-dimethylbenzamide (950 mg) was dissolved in ethyl acetate (10 mL), and thereto was added triethylamine (533 mg). The solution was cooled to 0° C. and 4′-trifluoromethylbiphenyl-2-carbonyl chloride (synthesized from 0.934 g of corresponding carboxylic acid) was added. The mixture was stirred overnight at room temperature. After removal of the insoluble materials by filtration, the filtrate was concentrated and purified by column chromatography on silica gel to give 4′-trifluoromethylbiphenyl-2-carboxylic acid (4-benzyloxy-2-dimethylcarbamoylphenyl)amide (1.23 g).
