Reaction Steps

A suspension of (4-amino-2-ethanesulfonylpyrimidin-5-yl)-(2-methoxyphenyl)-methanone (20.0 mg, 0.062 mmol, Example 6), 4-(4-methylpiperazino)aniline (16.6 mg, 0.087 mmol, Appollo 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° C. under microwave conditions for 1 hour. The resulting mixture was concentrated 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]-(2-methoxyphenyl)-methanone as a light yellow solid (10.6 mg). HRMS, observed: 419.2190; Calcd for (M+H)+: 419.2195.
