A mixture of 5-(4-chloro-2-oxo-1,2-dihydro-pyrrolo[2,3-b]pyridin-3-ylidenemethyl)-4-methyl-1H-pyrrole-2-carboxylic acid (2-morpholin-4-yl-ethyl)-amide (10 mg, 0.024 mmol), 3-chloro-4-fluoro-phenylamine (50 mg, 0.34 mmol), p-toluene sulfonic acid monohydrate (5 mg, 0.026 mmol) and 1 mL of 2-methoxyethyl ether was heated to 180-190° C. in a sealed tube for 6 hours, cooled to room temperature and concentrated. The residue was then purified using preparative TLC plates eluting with 10% methanol in dichloromethane to give 5-[4-(3-chloro-4-fluoro-phenylamino)-2-oxo-1,2-dihydro-pyrrolo[2,3-b]pyridin-3-ylidenemethyl]-4-methyl-1H-pyrrole-2-carboxylic acid (2-morpholin-4-yl-ethyl)-amide as an orange solid (yield is about 28%).
