Reaction Steps

3-Ethyl-9-methoxy-2,3,4,5-tetrahydro-1H-benzo[d]azepin-6-ylamine (50.01 mg, 0.2270 mmol), 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (67.4 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 (102 mg). The crude reaction was purified on silica gel (12 g Isco column) using a gradient of 0-10% methanol in methylene chloride and then isocratic 20% methanol in methylene chloride to yield 2-[5-Chloro-2-(3-ethyl-9-methoxy-2,3,4,5-tetrahydro-1H-benzo[d]azepin-6-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide as a beige foam. 1H-NMR (CDCl3) δ 11.10 (br s, 1H), 8.42 (br s, 1H), 8.02 (s, 1H), 7.40 (d, J=7.6 Hz, 1H), 7.15 (d, J=8.6 Hz, 1H), 6.95 (m, 1H), 6.77 (d, J=8.6 Hz, 1H), 6.43 (s, 1H), 3.89 (s, 3H), 3.12 (br s, 1H), 3.03 (d, J=4.8 Hz, 3H), 2.93 (br s, 1H), 2.60-2.41 (m, 6H), 1.00 (m, 3H).
