Participants

Reaction Steps

To a solution of 4-(3-cyano-4-hydroxymethylpyrrole-1-yl)benzoic acid ethyl ester (0.022 g) in tetrahydrofuran (1 mL) were added triethylamine (0.0082 g) and methane sulfonylchloride (0.0093 g) under ice-cooling. After warming to ambient temperature, this mixture was stirred for 30 minutes. The insoluble material of this reaction mixture was removed by filtration, and this filtrate was added to a mixture of ethanol (1.125 g) and sodium hydride (60%, 0.13 g), and this mixture was stirred for 5 hours. To this reaction mixture was added water, and this mixture was stirred at room temperature for 1 hours. To this reaction mixture was added 2 mol/L hydrochloric acid (3 mL), this mixture was extracted with ethyl acetate. This organic layer was washed with brine, concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: dichloromethane/methanol=88/12-81/19) to give the title compound (0.010 g).
