실험 절차

To a solution of (4-Formyl-2-methoxy-phenoxy)acetic acid methyl ester 71 (50 grams, 223 mmol) in methanol (500 mL) at 0° C. was added Sodium boro hydrate (4 grams, 106 mmol) in small portions, further stirred at 0° C. for 30 minutes and poured on to ice water (200 mL). The pH of mixture was adjusted to 2 with concentrated hydrochloric acid. Crude 72 was extracted into chloroform, dried over Na2SO4 and distilled to give 72 (40 grams, 62%) as a light yellow syrup.
