Procedure

N-{2,5-Difluoro-4-[(2-{[(3-hydroxyazetidin-1-yl)carbonyl]amino}pyridin-4-yl)oxy]phenyl}-N′-(4-fluorophenyl)cyclopropane-1,1-dicarboxyamide (30.0 mg) was suspended in ethanol (0.300 ml). After adding methanesulfonic acid (0.004 ml) at room temperature to form a solution, it was stirred at room temperature for 90 hours and 50 minutes. Ethanol (1 ml) was added, and then the precipitate was collected by filtration and washed with tert-butyl methyl ether (1 ml, three times). It was then dried under aeration at room temperature for 1 hour to give the title compound (26.3 mg, 75%) as white crystals.
