Reaction Steps
1,4-Dimethyl-indene-2-carboxylic acid (35.5 g) is hydrogenated in ethanol-water (700 ml-70 ml) over 10% palladium on carbon at ambient temperature. After filtration ethanol is evaporated. Water is added and the precipitated cis-2,3-dihydro-1,4-dimethyl-1H-indene-2-carboxylic acid is filrated. Yield 33.3 g, 93% M.p. 132°-135° C.
