Reaction Steps

To a stirred solution of N-[5-(2-amino-3-cyano-6-{2-[(4-methoxybenzyl)oxy]phenyl}-4-pyridinyl)-2-(dimethylamino)phenyl]-2-chloroacetamide (0.400 g, 0.738 mmol) in DMF (5 mL) was added aminomethylcyclopropane (0.192 mL, 2.214 mmol). The mixture was stirred at 60° C. for 2 hrs. After cooled to room temperature, the mixture was extracted with ethyl acetate and water. The separated organic phase was washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. Purification was carried out by column chromatography on silica gel (chloroform:methanol=100:2, hexane:ethyl acetate=1:2-1:3-1:5, 2 times) to give N1-[5-(2-amino-3-cyano-6-{2-[(4-methoxybenzyl)oxy]phenyl}-4-pyridinyl)-2-(dimethylamino)phenyl]-N2-(cyclopropylmethyl)-glycinamide as a yellow oil (0.130 g, yield 30%).
