Conditions

Temperature: 80 °C

Procedure

To a solution of 1-[2,4-bis(trifluoromethyl)benzyl]piperidine-4-carbaldehyde (1.11 g) in 2-propanol (10 mL) were added 4-[(2-hydroxy-2-methylpropyl)amino]-1,3-thiazol-2(5H)-one (616 mg) and piperidinium acetate (475 mg). The reaction mixture was stirred at 80° C. for 2 hr, and the solvent was evaporated under reduced pressure. Water was added to the residue, and the mixture was extracted with ethyl acetate. The extract was washed with 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 (ethyl acetate/hexane) to give the title compound (940 mg).
