Reaction Steps
To a solution of (2E)-3-(5-fluoro-6-{[(3R)-1-(2-octyn-1-yl)-3-pyrrolidinyl]amino}-3-pyridinyl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (155 mg) in methanol (3.5 ml) was added 4-methylbenzenesulfonic acid hydrate (122 mg) at 25° C. and then stirred at the same temperature for 1 hour. The mixture was concentrated under reduced pressure. The resulting residue was triturated with a mixed solvent of ethyl acetate, diisopropyl ether and methanol. Title compound (178 mg, 73%) was obtained as colorless powder.
