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 (1.2 g), N-ethyl-N-(1-methylethyl)propan-2-amine (0.79 mL) and 1-amino-2-methylpropan-2-ol (0.40 g) in DMF (10 mL) was added O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (1.03 g), and the mixture was stirred at 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, methanol/ethyl acetate), and the obtained solid was recrystallized from ethyl acetate/heptane to give the title compound (294 mg).
