Reaction Steps
To a solution of (1-oxo-2-ethyl-6,7-dichloro-5-indanyloxy)acetic acid (3.03 g., 0.01 mole) and sodium hydroxide (0.5 g., 0.0125 mole) in water (90 ml.) is added aqueous formaldehyde (1 ml., 0.012 mole). The resulting solution is stirred at 20°-25° C. for 41/2 days and acidified with hydrochloric acid. The tan powder which precipitates is recrystallized from ethanol-water affording 1.2 g. of (1-oxo-2-ethyl-2-hydroxymethyl-6,7-dichloro-5-indanyloxy)acetic acid which melts at 155°-157° C.
