実験手順

To a solution of lithium aluminium hydride (0.16 g) in THF (5.50 mL) was added a solution of methyl 2-fluoro-4-(1H-pyrazol-1-yl)benzoate (0.89 g) in THF (5.50 mL) under ice-cooling, and the mixture was stirred for 1 hr. To the reaction solution was added water, the insoluble substance was removed by filtration, and the filtrate was concentrated under reduced pressure to give the title compound (0.71 g) as a crude product.
