Participants

Conditions

Temperature: 80 °C

Procedure

To a solution of 1-[2,4-bis(trifluoromethyl)benzyl]piperidine-4-carbaldehyde (500 mg) in 2-propanol (10 mL) were added 4-({[1-(hydroxymethyl)cyclobutyl]methyl}amino)thiazol-2(5H)-one (474 mg) and piperidinium acetate (218 mg). The reaction mixture was stirred at 80° C. overnight, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) and recrystallized from ethyl acetate/heptane to give the title compound (258 mg).
