反应详情

To a solution of 1.48 g of tert-butyl(2S)-2-(3-formylphenoxy)propanoate in methanol (30 mL) was added 0.48 g of sodium borohydride under ice-cooling, followed by stirring for 1 hour. The reaction solution was diluted with ethyl acetate, added with water, neutralized with 1 M hydrochloric acid, and extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to obtain 1.38 g of tert-butyl(2S)-2-[3-(hydroxymethyl)phenoxy]propanoate as a colorless oily substance.
