Reaction Conditions

Reaction Steps

To a solution of 4-{[(3R)-2-oxopyrrolidin-3-yl]amino}-1,3-thiazol-2(5H)-one (140 mg) and 1-[2,4-bis(trifluoromethyl)benzyl]piperidine-4-carbaldehyde (358 mg) in 2-propanol (5 mL) was added piperidinium acetate (102 mg). The reaction mixture was stirred at 80° C. for 6 hr and concentrated under reduced pressure. Water was added to the residue, and the mixture was extracted with ethyl acetate. The extract 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 (ethyl acetate/methanol). The obtained solid was recrystallized from ethyl acetate/heptane to give the title compound (80 mg).
