Procedure

2-Allyl-2-methyl-5-methoxy-6,7-dichloro-1-indanone is prepared following substantially the same procedure described in Example 5, Step E, using the following substances: 2-methyl-5-methoxy-6,7-dichloro-1-indanone (14.7 g., 0.06 mole), sodium hydride (1.7 g., 0.072 mole), 1,2-dimethoxyethane (500 ml.) and allyl bromide (8 ml.). The above procedure gives 11.0 g. of 2-allyl-2-methyl-5-methoxy-6,7-dichloro-1-indanone which after recrystallization from methyl cyclohexane melts at 58° C.
