Procedure
3-(2-Methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (1.00 g, 4.54 mmol) and 2-(2,5-dichloro-pyrimidin-4-ylamino)-benzoic acid ethyl ester (1.29 g, 4.13 mmol) were dissolved in ethanol (40.00 mL, 685 mmol) and 10-camphorsulfonic acid (1.15 g, 4.95 mmol) was added. The reaction was microwaved on 300 watts, 120° C. for 40 minutes and then concentrated under reduced pressure. The residue was taken up in DCM (100 mL) and washed with sat. NaHCO3 (100 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. Purification by amine capped silica gel chromatography using a gradient of 0-40% EtOAc/hex as the eluting solvent to obtain 2-{5-chloro-2-[3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-benzoic acid ethyl ester as a yellow solid (1.22 g, 60%). m.p.=78-80° C.; LCMS (m/e) 496 (M+H); 1H-NMR (CDCl3, 400 MHz) δ 11.16 (s, 1H), 8.85 (d, 1H, J=8.5 Hz), 8.14 (s, 1H), 8.11 (d, 1H, J=8.0 Hz), 7.56-7.45 (m, 1H), 7.35 (s, 1H), 7.30-7.20 (m, 1H), 7.13-7.01 (m, 2H), 6.93 (s, 1H), 4.45 (q, 2H, J=7.1 Hz), 3.60-3.50 (m, 2H), 3.39 (s, 3H), 3.0-2.88 (m, 4H), 2.80-2.67 (m, 6H), 1.45 (t, 3H, J=7.1 Hz).
