A stirred suspension of (1-oxo-2-ethyl-6,7-dichloro-5-indanyloxy)acetic acid (12.12 g., 0.04 mole) in water (400 ml.) is cooled to 5° C. and treated during a one hour period with solution of potassium borohydride (4.0 g., 0.075 mole) in water (200 ml.). The reaction is stirred for 1 hour then acidified with hydrochloric acid affording 10.6 g. (87%) of (1-hydroxy-2-ethyl-6,7-dichloro-5-indanyloxy)acetic acid which melts at 121°-122° C. after recrystallization from benzene.
