Participants

Reaction Steps

Ethyl [1-oxo-2-(4-aminomethylphenyl)-2-methyl-6,7-dichloro-5-indanyloxy]acetate hydrochloride (1.57 g., 0.0034 mole), sodium bicarbonate (1.15 g., 0.0136 mole), absolute ethanol (50 ml.) and water (50 ml.) are combined and heated at reflux for 1.5 hours leaving a solution which is filtered, then neutralized with 1N hydrochloric acid (10.26 ml., 0.01026 mole) to precipitate 900 mg. of [1-oxo-2-(4-aminomethylphenyl)-2-methyl-6,7-dichloro-5-indanyloxy]acetic acid sodium salt which melts at 270°-271° C. after drying.
