Procedure
To a mixture of 2-(4-methoxycarbonylphenyl)methoxy-4-methylaniline (420 mg) and 37% formaldeyde solution (69.7 mg) in a mixture of methanol (10 ml) and actic acid (0.1 ml) was added soduim cyanoborohydride (146 mg) and the mixture was stirred at amibient temperature for 3 hours. The solution was diluted with ethyl acetate (30 ml) and washed successively with saturated aqueous sodium hydrogen carbonate, water and brine. The organic solution was dried over magnesium sulfate and the solvent was evaporated in vacuo. The residue was purified by silica gel column (chloroform) to give 2-(4-methoxycarbonylphenyl)methoxy-4-methyl-N-methylaniline (356 mg).
