Sodium sulfate decahydrate → [3-(methoxymethoxy)-1-(2-methylphenyl)-1H-pyrazol-4-yl]methanol

Participants

Reaction Steps

To a solution of ethyl 3-(methoxymethoxy)-1-(2-methylphenyl)-1H-pyrazole-4-carboxylate (2.39 g) in tetrahydrofuran (60 mL) was added lithium aluminum hydride (0.323 g) at 0° C. and the mixture was stirred at room temperature for 16 hrs. Sodium sulfate decahydrate (2.78 g) was added to the reaction mixture and the mixture was stirred at room temperature for 1 hr. After removing the precipitate by filtration, and the filtrate was concentrated. The residue was subjected to silica gel column chromatography and eluted with ethyl acetate-hexane (1:1-4:1, v/v) to give [3-(methoxymethoxy)-1-(2-methylphenyl)-1H-pyrazol-4-yl]methanol as a pale-yellow oil (1.84 g, yield 90%).
