2-Methyl-2-propargyl-5-methoxy-6,7-dichloro-1-indanone is prepared by following substantially the same procedure described in Example 4, Step B, using the following reagents: 2-methyl-5-methoxy-6,7-dichloro-1-indanone (14.7 g., 0.06 mole), sodium hydride (1.72 g., 0.072 mole), 1,2-dimethoxyethane (500 ml.) and propargyl bromide (8 ml.). The above procedure gives 16.5 g. (97%) of 2-methyl-2-propargyl-5-methoxy-6,7-dichloro-1-indanone which after recrystallization from methyl cyclohexane melts at 118°C.
