Procedure

A suspension of (4-amino-2-ethanesulfonyl-pyrimidin-5-yl)-(2,6-difluoro-3-methoxy-phenyl)-methanone (20.0 mg, 0.056 mmol, Example 89) and 1-(4-amino-piperidin-1-yl)-ethanone (21.1 mg, 0.148 mmol, prepared as described in U.S. Pat. No. 5,817,828) in isopropyl alcohol (2.5 mL) was heated at 120° C. in a sealed tube under microwave conditions for 0.3 to 1 hour. The resulting reaction mixture was evaporated in vacuo and crude product was purified on silica gel with 95:5 of dichloromethane/methanol to give 1-[4-[4-amino-5-(2,6-difluoro-3-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidin-1-yl]-ethanone as a white solid (18.3 mg). MS (M+H)+, 406.
