Procedure

A mixture of 2-(2,5-dichloro-pyrimidin-4-ylamino)-N-methylbenzamide (50 mg, 0.17 mmol), 2-amino-5-methyl-8,9-dihydro-5H-7-oxa-5-aza-benzocyclohepten-6-one (49 mg, 0.25 mmol) and camphorsulformic acid (4 mg, 0.02 mmol) in IPA (5 mL) was microwave-heated at 120° C. for 3.5 h. The mixture was concentrated and chromatographed with preparative TLC (methylene chloride and ethyl acetate (4:1)) to give 54 mg of 2-[5-chloro-2-(5-methyl-6-oxo-5,6,8,9-tetrahydro-7-oxa-5-aza-benzocyclohepten-2-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide (71%): 1H NMR (300 MHz, CDCl3) δ 8.33 (d, 1H), 7.95 (s, 1H), 7.56 (d, 1H), 7.43 (dd, 1H), 7.34 (d, 1H), 7.26 (m, 1H), 7.1 (t, 1H), 7.05 (d, 1H). 4.35 (t, 2H), 3.3 (s, 3H), 2.9 (s, 3H), 2.85 (t, 2H); MS (m/e): 453.3 (M+1).
