Procedimiento

To a solution of 4-fluoro-3-methoxyaniline (0.98 g 6.9 mmol) in ethanol (20 ml) was added glyoxal 1,1-dimethyl acetal (0.89 g 8.27 mmol). Pd/C 5% (50 mg) was added and the mixture hydrogenated. Removal of the catalyst by filtration and evaporation of solvent in vacuo gave N-(2,2-dimethoxyethyl)-4-fluoro-3-methoxyaniline 1.6 g
