Procedure

A mixture of 6,7-dichloro-2-cyclopentyl-5-hydroxy-2-methyl-2,3-dihydro-1H-inden-1-one (6.0 g, 20 mmole), 4-bromobutanenitrile (3.28 g, 22 mmole), and potassium carbonate (3.1 g, 22 mmole) in dimethylformamide (50 ml) was stirred at 60°-65° for four hours. The reaction mixture was poured into water and extracted with diethyl ether. The organic layer was washed successively with water and brine, dried over magnesium sulfate, and concentrated in vacuo to a solid residue (4.7 g). Recrystallization from butyl chloride-hexane afforded the analytically pure title compound, m.p. ca. 112°.
