Procedure

To a mixture of 22 g. of methyl 6-methyl-2-naphthylacetate, 2.5 g. of sodium hydride and 150 ml. of 1,2-dimethoxyethane, 25 g. of methyliodide are added. The reaction mixture is allowed to stand for several hours; then it is diluted with ethanol followed by water and extracted with methylene chloride. The extracts are combined, washed with water to neutrality, dried over sodium sulfate, filtered, and evaporated to yield methyl 6-methyl-2-naphthyl-α-methylacetate. This derivative is hydrolyzed by means of the process described in Part H of Example 2 to obtain 6-methyl-2-naphthyl-α-methylacetic acid.
