Reaction Steps

A suspension of (4-amino-2-ethanesulfonylpyrimidin-5-yl)-(2-methoxyphenyl)-methanone (26.6 mg, 0.0828 mmol, Example 6) and 4-(4-isopropylpiperazin-1-yl)phenylamine (19.5 mg, 0.0889 mmol) in isopropanol (2.5 mL) was placed in a sealed tube and heated at 110° C. under microwave conditions for 1 hour. The resulting mixture was concentrated and the crude product was purified on silica gel with 95:5 of dichloromethane/methanol to give [4-amino-2-[4-(4-isopropyl-piperazin-1-yl)-phenylamino]-pyrimidin-5-yl]-(2-methoxy-phenyl)-methanone as a light yellow solid (15.6 mg, 42% yield). HRMS, observed: 447.2507; Calcd for (M+H)+: 447.2503.
