Reaction Steps

To a solution of N-{2-[4-({3-chloro-4-[3-(trifluoromethyl)phenoxy]phenyl}amino)-5H-pyrrolo[3,2-d]pyrimidin-5-yl]ethyl}-2-(methylsulfonyl)acetamide (150 mg) in ethyl acetate (10 mL) was added 4-methylbenzenesulfonic acid monohydrate (55.4 mg) at room temperature. The mixture was stirred at room temperature for 20 hrs, and the solvent was evaporated under reduced pressure. The precipitated crystals were collected by filtration and washed with ethyl acetate and diisopropyl ether to give the title compound (150.3 mg) as colorless crystals.
