Procedure

To a solution of 1-[2,4-bis(trifluoromethyl)benzyl]azepane-4-carbaldehyde (133.2 mg) in 2-propanol (1.89 mL) were added 4-[(2-hydroxy-2-methylpropyl)amino]-1,3-thiazol-2(5H)-one (142 mg) and piperidinium acetate (54.7 mg). The reaction mixture was stirred at 60° C. overnight, cooled to room temperature, and diluted with ethyl acetate. The mixed solution was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (86.3 mg).
