Reaction Steps

To a solution of (5Z)-5-({1-[2,4-bis(trifluoromethyl)benzyl]piperidin-4-yl}methylidene)-4-{[(2Z)-4-(diethylamino)but-2-en-1-yl]amino}-1,3-thiazol-2(5H)-one (162 mg) in ethyl acetate (3 mL) was added tosylic acid monohydrate (55 mg) at room temperature. The reaction mixture was stirred at 60° C. for 5 min. The solvent was evaporated under reduced pressure, and the residue was recrystallized from ethyl acetate/heptane to give the title compound (179 mg).
