3-Ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (75 mg 0.20 mmol), 3-(2,5-Dichloro-pyrimidin-4-ylamino)-azepan-2-one (57 mg, 0.30 mmol) and 81 μl of 4N HCl in dioxanes were combined into 1 ml IPA in a microwave tube. The reaction was heated to 120° C. for 40 minutes in the microwave. The reaction was poured into water (50 ml) and saturated sodium bicarb (90 ml) and extracted 3 times with 25 ml portions of methylene chloride. The combined organic was dried over magnesium sulfate, filtered and evaporated to a brown oil. The crude reaction was purified on a 12 g Isco silica gel column using 0-20% methanol in methylene chloride as the eluent to yield 3-[5-Chloro-2-(3-ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino)-pyrimidin-4-ylamino]-azepan-2-one (22.33 mg, 19%).
