Reaction Steps

A suspension of (4-amino-2-ethanesulfonyl-pyrimidin-5-yl)-(3-fluoro-phenyl)-methanone (20.1 mg, 0.0650 mmol, Example 3), 4-(4-methylpiperazino)aniline (15.8 mg, 0.0826 mmol, Appolo Chemical) and p-toluenesulfonic acid hydrate (15 mg, 0.0777 mmol, Aldrich) in isopropanol (2.5 mL) was placed in a sealed tube and heated at 100 to 110° C. under microwave conditions for 1 hour. The resulting mixture was evaporated in vacuo and the crude product was purified on silica gel with 95:5 of dichloromethane/methanol to give [4-amino-2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-pyrimidin-5-yl]-(3-fluoro-phenyl)-methanone as a light yellow solid (16.4 mg, 68% yield). HRMS, observed: 407.1994; Calcd for (M+H)+: 407.1990.
