Reaction Steps

By following substantially the procedure in Example 8, Step B, but substituting for (+) 6,7-dichloro-2-cyclopentyl-2,3-dihydro-5-hydroxy-2-methyl-1H-inden-1-one an equimolar quantity of (+) 2-butyl-6,7-dichloro-2-cyclopentyl-2,3-dihydro-5-hydroxy-1H-inden-1-one described therein, there is obtained (+) 4-[(2-butyl-6,7-dichloro-2-cyclopentyl-2,3-dihydro-1-oxo-1H-inden-5-yl)oxy]butanoic acid which melts at 139°-139.5° C., [α]D25 +18.4° (C=5, ethanol).
