Procedure
Sodium methoxide (28.4 g., 0.522 mole) is added to a stirred mixture of 2-(4-bromophenyl)-5-methoxy-6,7-dichloro-1-indanone (134.6 g., 0.348 mole), iodomethane (217 ml., 3.48 mole), dry benzene (1700 ml.) and dry dimethylformamide (1700 ml.) under nitrogen in an ice-water bath. The reaction mixture is left to come to ambient temperature over 2 hours, then poured into water (8 l.) to precipitate 92.2 g. of 2-(4-bromophenyl)-2-methyl-5-methoxy-6,7-dichloro-1-indanone, m.p. 200°-203° C., which is not soluble in the benzene present.
