Procedure

To a solution of N-[(5Z)-5-({1-[2,4-bis(trifluoromethyl)benzyl]piperidin-4-yl}methylidene)-2-oxo-2,5-dihydro-1,3-thiazol-4-yl]glycine hydrochloride (500 mg), N-ethyl-N-(1-methylethyl)propan-2-amine (0.33 mL) and 1-methylpiperazine (0.11 mL) in DMF (5 mL) was added O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (429 mg), and the mixture was stirred at so room temperature for 2 hr. Water was added to the reaction mixture, 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 (NH, hexane/ethyl acetate), and the solid was recrystallized from diisopropyl ether/heptane to give the title compound (85 mg).
