Into a microwave vial was placed 7,7-difluoro-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamine (79 mg, 0.00040 mol) and 2-(2,5-dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (100 mg, 0.0003 mol) in isopropyl alcohol (4 mL, 0.05 mol). 4N HCl-dioxane (0.04 g, 0.0003 mol) was added to the reaction mixture and the contents subjected to microwaves at 120° C. for 10 min. The reaction mixture was resubjected to the same microwave conditions for an additional 10 min. A solid had precipitated out of the reaction mixture, was collected by filtration then redissolved in methylene chloride (6 mL) and washed with sat. aqueous sodium bicarbonate (1×5 mL) and water (2×5 mL). The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuo to give 2-[5-Chloro-2-(7,7-difluoro-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide as a brown solid (38 mg, 29%). MP: 160-168° C.; 1HNMR (400 MHz, DMSO-d6) δ 11.59 (s, 1H), 9.46 (s, 1H), 8.80 (d, 1H, J=4.5 Hz), 8.74 (d, 1H, J=7.6), 8.26 (s, 1H), 7.79 (d, 1H, J=7.8 Hz), 7.61 (s, 1H), 7.53 (t, 1H, J=7.6), 7.45 (d, 1H, J=7.8), 7.2 (t, 1H, J=7.3), 2.85 (d, 3H, J=4 Hz), 2.69-2.77 (m, 4H), 2.06 (m, 4H); MS (m/e) 458 (M+1).
