Ethanol → (1-Methyl-4-phenyl-1H-imidazol-2-yl)-methanol

Participants

Reaction Steps

To a solution of 1-methyl-4-phenyl-1H-imidazole-2-carbaldehyde (7.24 g) in tetrahydrofuran (50 mL)-ethanol (10 mL) was gradually added sodium borohydride (1.47 g) at room temperature and the mixture was stirred at room temperature for 30 min. Water was added to the reaction mixture and the precipitated crystals were collected by filtration to give (1-methyl-4-phenyl-1H-imidazol-2-yl)methanol as colorless crystals (5.71 g, yield 78%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 191-192° C.
