A mixture of 7-amino-1,1-dimethyl-1,2,4,5-tetrahydrobenzo[c]azepin-3-one (40 mg), 2-(2,5-dichloropyrimidin-4-ylamino)-3-fluoro-N-methylbenzamide (50 mg), and 2 drops of 4 N HCl/dioxane in IPA (3 mL) were microwave-heated at 120° C. for 1.5 hours. The mixture was concentrated to afford crude 2-(2-(3-(3-amino-3-oxopropyl)-4-(prop-1-en-2-yl)phenylamino)-5-chloropyrimidin-4-ylamino)-3-fluoro-N-methylbenzamide. The crude mixture was stirred for 4 hours in TFA and concentrated. Purification by semi-preparative HPLC provided 2-(5-chloro-2-(1,1-dimethyl-3-oxo-2,3,4,5-tetrahydro-1H-benzo[c]azepin-7-ylamino)pyrimidin-4-ylamino)-3-fluoro-N-methylbenzamide (45.7 mg) as a TFA salt: 1H NMR (300 MHz, CD3OD) δ 8.3 (s, 1H), 7.7-7.5 (m, 3H), 7.65 (s, 1H, slowly exchanging NH), 7.4 (d, 1H), 7.32 (d, 1H), 7.28 (dd, 1H), 3.0 (m, 2H), 3.0 (s, 3H), 2.7 (m, 2H), 1.8 (s, 6H).
