HCID 67264447N-{(1R,2R)-2-[5-Chloro-2-(7,7-difluoro-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamideYield 50%

Procedure

Into a microwave vial was placed 7,7-difluoro-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamine (79 mg, 0.00040 mol) and N-[(1R,2R)-2-(2,5-dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (100 mg, 0.0003 mol) in isopropyl alcohol (4 mL, 0.05 mol) with 4N HCl-dioxane (0.04 g, 0.0003 mol). The reaction was subjected to microwaves at 120° C. for 10 min. HPLC and LCMS indicated trace starting material remaining. The reaction mixture was resubjected to microwaves for an additional 10 min. A tan solid had precipitated out of solution and was collected by filtration. The solid was redissolved in methylene chloride (5 mL) and washed with sat. 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 N-{(1R,2R)-2-[5-Chloro-2-(7,7-difluoro-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamide as a brown solid (75 mg, 40%). MP: 118-128° C.; 1HNMR (400 MHz, DMSO-d6) δ 9.16 (s, 1H), 7.93 (s, 1H), 7.62 (s, 1H), 7.46 (d, 1H, J=8 Hz), 7.18 (d, 1H, J=8 Hz), 7.07 (d, 1H, J=8 Hz), 6.71 (d, 1H, J=8 Hz), 3.84 (m, 1H), 2.94 (s, 3H), 2.70 (m, 4H), 1.99-2.09 (m, 6H), 1.71 (m, 2H), 1.18-1.39 (m, 5H); MS (m/e) 500 (M+1).
