Procedure

A suspension of 7-amino-1,1-dimethyl-1,2,4,5-tetrahydrobenzo[c]azepin-3-one (46 mg), 2-(2,5-dichloropyrimidin-4-ylamino)-N,3-dimethylbenzamide (42 mg), and camphorsulfonic acid (40 μL of a 100 mg/mL aqueous solution) were heated in isopropanol (2 mL) for 4 hours at 120° C. using microwave irradiation. The solvent was evaporated to afford crude 2-(2-(3-(3-amino-3-oxopropyl)-4-(prop-1-en-2-yl)phenylamino)-5-chloropyrimidin-4-ylamino)-N,3-dimethylbenzamide The crude mixture was dissolved in TFA and allowed to stand for 4 hours, then 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)-N,3-dimethylbenzamide as the TFA salt. The non-salt was obtained by stirring the TFA salt in acetonitrile with 300 mg of MP-carbonate (Argonaut, 2.91 mmol/g) for 2 days. The resin was separated by filtration, then washed with methanol and methylene chloride. The filtrate was concentrated and the residue triturated with ethyl ether to provide 14 mg of the neutral compound: 1H NMR (300 MHz, CDCl3 with 5% CD3OD) δ 8.05 (s, 1H), 7.5-7.4 (m, 2H), 7.35 (dd, 1H), 7.3 (d, 1H), 7.15 (d, 1H), 7.1 (dd, 1H), 2.9 (s, 3H), 2.8 (m, 2H), 2.6 (m, 2H), 2.3 (s, 3H) 1.8 (s, 6H).
