Reaction Steps

A mixture of (4-methoxyphenyl)methanamine (6.9 g) and dimethyl itaconate (7.9 g) was stirred at 120° C. for 2 hours. After cooling, ethyl acetate was added to the reaction solution. The organic layer was washed with 1 N hydrochloric acid, a saturated aqueous solution of sodium bicarbonate, and saturated saline in this order and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain the title compound (12.7 g).
