Procedure
Lithium aluminium hydride (0.258 g) was added to a solution of methyl 1-(6-benzyloxy-2-naphthylmethyl)-4-phenylpyrrole-3-carboxylate (3.04 g) in tetrahydrofuran (30 ml) at 0° C., and the mixture was stirred at room temperature for one hour. Sodium sulfate decahydrate (2.19 g) and hexane (30 ml) were added to the reaction mixture and the mixture was stirred at room temperature for 30 minutes. After the precipitate was removed by filtration, the filtrate was concentrated. The colorless crystals obtained were collected by filtration to yield [1-(6-benzyloxy-2-naphthylmethyl)-4-phenyl-3-pyrrolyl]methanol (2.54 g, yield: 89%). This was recrystallized from ethyl acetate-hexane. Melting point: 116–117° C.
