40% methylamine methanol solution (5 ml) was added to a methanol solution (5 ml) of 1-allyl-5-[3-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)propoxy]-1H-pyrazole-3-carboxylic acid ethyl ester (0.5 g, 1.1 mmol) and the mixture was stirred at room temperature for 3 days. The solution was concentrated under reduced pressure and the residue was purified by basic silica gel column chromatography (n-hexane:ethyl acetate=5:1→0:1). The purified product was concentrated under reduced pressure and the residue was recrystallized from a solvent mixture of ethyl acetate-diisopropylether to obtain 1-allyl-5-[3-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)propoxy]-1H-pyrazole-3-carboxylic acid methylamide (0.32 g, 67% yield) as white powder.
