Reaction Steps

2-(5-Chloro-2-{6-[4-(2-hydroxy-ethyl)-piperazin-1-yl]-1-methoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamino}-pyrimidin-4-ylamino)-N-methyl-benzamide (4.90 g, 8.45 mmol) and 2.5 M of HCl in ethanol (13.5 mL, 33.8 mmol) were heated until they dissolved in ethanol (164 mL). The reaction was concentrated two times from ethanol, then warmed in a small amount of ethanol until completely dissolved. This solution was allowed to cool slowly with a stirring (<100 rpm). A solid preciptate formed quickly before the solution had cooled. This mixture was allowed to stir until ambient temperature was achieved and then filtered. The solid was washed with ethanol followed by ether then directly pumped dry under high vac to give 2-(5-chloro-2-{6-[4-(2-hydroxy-ethyl)-piperazin-1-yl]-1-methoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-2-ylamino}-pyrimidin-4-ylamino)-N-methyl-benzamide hydrochloride (5.3 grams, quantitative yield). 1H-NMR (MeOD, 400 MHz) δ 8.55 (s, 1H), 8.17 (s, 1H), 7.80 (d, J=7.7 Hz, 1H), 7.55 (t, J=6.8 Hz, 1H), 7.46 (broad s, 1H), 7.36 (t, J=7.2 Hz, 1H), 7.23 (d, J=8.5 Hz, 1H), 4.00-3.95 (m, 4H), 3.83-3.72 (m, 5H), 3.73 (s, 3H), 3.65-3.59 (m, 2H), 3.47-3.38 (m, 5H), 2.95 (s, 3H), 2.72-2.65 (m, 1H), 2.44-2.38 (m, 1H), 2.29-2.28 (m, 1H), 2.19-2.12 (m, 1H), 1.59-1.49 (m, 1H).
