Procedure

To a mixture of 22 g. of methyl 6-methyl-2-naphthylacetate, 2.5 g. of sodium hydroxide and 150 ml. of 1,2-dimethoxyethane, 25 g. of methyl iodide are added. The reaction mixture is allowed to stand for several hours and is then 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 treatment with sodium carbonate in aqueous methanol, and the reaction mixture is acidified with hydrochloric acid, washed, dried and evaporated to dryness to yield 2-(6'-methyl-2'-naphthyl)propionic acid.
