Reaction Steps
Sodium borohydride (0.46 g) was added to a solution of methyl 3-(2-formylpyrrol-1-yl)-4-hydroxybenzoate (3.0 g) in tetrahydrofuran (30 ml) and the mixture was stirred for 1 hour at ambient temperature. The reaction mixture was added to the mixture of ethyl acetate and water and adjusted to pH 7.5 with 6N-hydrochloric acid. The separated organic layer was washed with water, dried over magnesium sulfate and evaporated in vacuo to give methyl 4-hydroxy-3-(2-hydroxymethylpyrrol-1-yl)benzoate (2.54 g).
