実験手順

A mixture of 0.90 g (2.52 mmol) of ethyl 4-chloro-6-[4-formylphenoxy)-1-methyl-2-indolecarboxylate, 0.10 g (2.52 mmol) of sodium borohydride and 20 ml of ethanol was stirred at 0° C. for 2 hours. The reaction mixture was poured onto ice water. The resulting mixture was then extracted three times with ethyl acetate. The combined extracts were washed with saturated sodium chloride aqueous solution. After drying over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure to give 0.91 g (>99%) of ethyl 4-chloro-6-[4-(hydroxymethyl)phenoxy]-1-methyl-2-indolecarboxylate.
