Reaction Steps

N-[4-({2-[({4-[3-(Dimethylamino)azetidin-1-yl]piperidin-1-yl}carbonyl)amino]pyridin-4-yl}oxy)-2-fluorophenyl]-N′-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide (31.7 mg) was suspended in acetone (0.317 ml). To this was added a 5M hydrochloric acid (0.010 ml) and water (0.0059 ml) at room temperature, followed by stirring for 5 hr. After adding of acetone (0.317 ml), insoluble matter was collected by filtration and washed with acetone (0.159 ml, twice). This was dried under aeration at room temperature, then hot air-dried at 60° C. to provide the titled compound as white powder (32.1 mg, 96%).
