Reaction Steps

3-Ethyl-9-methoxy-2,3,4,5-tetrahydro-1H-benzo[d]azepin-6-ylamine (50.01 mg, 0.2270 mmol), N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (77.0 mg, 0.227 mmol) and 10-camphorsulfonic acid (79.1 mg, 0.340 mmol) were charged to 2 ml IPA in a microwave tube. The reaction was heated to at 120° C. for 40 minutes. Pour reaction into water (50 ml) and saturated sodium bicarb (90 ml) and extract 3 times with 25 ml portions of methylene chloride. Dry combined organic over magnesium sulfate, filter and evaporate to a brown oil (87 mg). The crude reaction was purified on silica gel (12 g Isco column) using a gradient of 0-20% methanol in methylene chloride and then isocratic 20% methanol in methylene chloride to yield N-{(1R,2R)-2-[5-Chloro-2-(3-ethyl-9-methoxy-2,3,4,5-tetrahydro-1H-benzo[d]azepin-6-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamide as an off white foam. 1H-NMR (CDCl3) δ 7.88 (s, 1H), 7.11 (d, J=8.6 Hz, 1H), 6.78 (d, J=8.6 Hz, 1H), 6.38 (s, 1H), 5.18 (br s, 1H), 3.81 (s, 3H), 3.10 (br s, 2H), 2.72 (s, 3H), 2.68-2.49 (m, 6H), 2.18-2.00 (m, 2H), 1.82-1.69 (m, 2H), 1.40-1.18 (m, 4H), 1.07 (t, J=7 Hz, 3H).
