반응 단계
Lithium aluminium hydride (1.93 g) was added to a solution of ethyl 3-methyl-1-(2-pyridyl)-1H-pyrazole-4-carboxylate (15.00 g) in tetrahydrofuran (150 ml) at 0° C., and the mixture was stirred at room temperature for one hour. Sodium sulfate decahydrate (21.03 g) and hexane (100 ml) were added to the reaction mixture, and the mixture was stirred at room temperature for one hour. After the precipitate was removed by filtration, the filtrate was concentrated. The crystals obtained were collected by filtration to yield [3-methyl-1-(2-pyridyl)-1H-pyrazol-4-yl]methanol (11.38 g). This was recrystallized from acetone-hexane. Melting point: 116–117° C.
