Reaction Steps
Lithium aluminium hydride (1.33 g) was added to a solution of ethyl 1-(4-benzyloxybenzyl)-3-(4-fluorophenyl)-1H-pyrazole-4-carboxylate (15.1 g) in tetrahydrofuran (300 ml) at 0° C., which was stirred at room temperature for 1 hour. Sodium sulfate decahydrate (12.26 g) and hexane (100 ml) was added to the reaction mixture, which was stirred at room temperature for 1 hour. After the precipitate was removed by filtration, the filtrate was concentrated to obtain 1-(4-benzyloxybenzyl)-3-(4-fluorophenyl)-1H-pyrazol-4-ylmethanol (12.9 g, yield 95%) as colorless crystals. This was recrystallized from ethyl acetate-hexane. Melting point: 112–113° C.
