Procedure
Into a microwave vial was added 7,7-difluoro-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamine (55 mg, 0.00028 mol) and (2,5-dichloro-pyrimidin-4-yl)-(2-methoxy-4-morpholin-4-yl-phenyl)-amine (80 mg, 0.0002 mol) in isopropyl alcohol (4 mL, 0.05 mol). To this reaction mixture was added 4N HCl-dioxane (0.03 g, 0.0002 mol). The reaction was subjected to microwaves at 120° C. for 10 min. The reaction mixture was resubject to the microwave conditions (120° C. for 10 min) The reaction mixture was purified by prep HPLC using the Gilson system and a gradient of 30-50% acetonitrile-water. The peaks corresponding to product were combined extracted with methylene chloride and washed with bicarbonate and dried to give 5-Chloro-N*2*-(7,7-difluoro-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-yl)-N*4*-(2-methoxy-4-morpholin-4-yl-phenyl)-pyrimidine-2,4-diamine a tan solid (34 mg, 30% yield). MP: 180-184° C.; 1HNMR (400 MHz, DMSO-d6) δ 9.52 (s, 1H), 8.66 (broad s, 1H), 8.12 (s, 1H), 7.43 (s, 1H), 7.41 (d, 1H, J=8.84 Hz), 7.15 (d, 1H, J=8 Hz), 6.98 (d, 1H, 8 Hz), 6.71 (s, 1H), 6.54 (d, 1H, J=9 Hz), 3.78 (s, 7H), 3.18 (dd, 4H, J=5, 9 Hz), 2.65 (dd, 2H, J=5, 10 Hz), 1.97 (m, 4H); MS (m/e) 516 (M+1).
