Procedure

To a solution of (4-Formylphenoxy)acetic acid methyl ester 68 (160 grams, 825 mmol) in methanol (800 mL) at 0° C. was added Sodium borohydrate (18 grams, 476 mmol) in small portions, further stirred at 0° C. for 2 hours and poured on to ice water (1500 mL). The pH of mixture was adjusted to 2 with concentrated hydrochloric acid. Crude 69 was extracted into chloroform, dried over Na2SO4, distilled and purified by column chromatography on silica gel using hexane:ethyl acetate (7:3) to give 69 (100 grams, 62%) as white powder
