Procedure

41.5 g (0.18 mole) of 1,3-dimethoxy-2-(3,3,3-trifluoroprop-1-ynyl)-benzene are dissolved in tetrahydrofuran and hydrogenated in the presence of palladium-on-charcoal at room temperature under normal pressure. The catalyst is filtered off over diatomaceous earth and washed with tetrahydrofuran and the filtrate is concentrated. Drying under reduced pressure gives crystalline 1,3-dimethoxy-2-(3,3,3-trifluoropropyl)-benzene (yield 87%).
