Participants

Reaction Steps

A suspension of (4-amino-2-ethanesulfinyl-pyrimidin-5-yl)-(2-methoxy-5-methyl-phenyl)-methanone (22.3 mg, 0.0698 mmol, Example 325) and 1-(4-amino-piperidin-1-yl)-ethanone (14.9 mg, 0.105 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-methoxy-5-methyl-benzoyl)-pyrimidin-2-ylamino]-piperidin-1-yl]-ethanone as a white solid (23.1 mg). MS (M+H)+, 384.
