HCID 866340262-{5-Chloro-2-[3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-N-prop-2-ynyl-benzamide

実験手順

2-Amino-N-prop-2-ynyl-benzamide (4.20 g, 24.1 mmol) was dissolved in N,N-dimethylformamide (100 mL, 1.290 mol) and potassium carbonate (5.00 g, 36.2 mmol) was added. 2,4,5-Trichloro-pyrimidine (3.32 mL, 28.9 mmol) was added and the reaction was stirred for 48 hours. The reaction was concentrated under reduced pressure and the residue was taken up in DCM (300 mL) and washed with water (300 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. Purification by silica gel chromatography using a gradient of 0-50% EtOAc/hex as the eluting solvent to obtain 2-(2,5-dichloro-pyrimidin-4-ylamino)-N-prop-2-ynyl-benzamide as a pale yellow solid (298 mg, 4%). m.p.=188-191° C.; LCMS (m/e) 321 (M+H); 1H-NMR (CDCl3, 400 MHz) δ 11.53 (s, 1H), 8.76 (d, 1H, J=8.5 Hz), 8.25 (s, 1H), 7.66-7.53 (m, 2H), 7.23-7.14 (m, 1H), 6.39 (bs, 1H), 4.34-4.25 (m, 2H), 2.34 (t, 1H, J=2.5 Hz). 1387c) 2-{5-Chloro-2-[3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-N-prop-2-ynyl-benzamide was prepared from 3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine and 2-(2,5-dichloro-pyrimidin-4-ylamino)-N-prop-2-ynyl-benzamide in an analogous manner to Example 308c. Product isolated as a white solid (59 mg, 34%). m.p.=165-167° C.; LCMS (m/e) 505 M+H); 1H-NMR (CDCl3, 400 MHz) δ 10.91 (s, 1H), 8.69 (d, 1H, J=8.9 Hz), 8.11 (s, 1H), 7.55 (d, 1H, J=7.5 Hz), 7.50-7.43 (m, 1H), 7.35 (s, 1H), 7.28-7.22 (m, 1H), 7.16-7.08 (m, 1H), 7.04 (d, 1H, J=8.8 Hz), 6.87 (s, 1H), 6.32 (bs, 1H), 4.32-4.26 (m, 2H), 3.56 (t, 2H, J=5.7 Hz), 3.39 (s, 3H), 2.97-2.87 (m, 4H), 2.80-2.69 (m, 6H), 2.35-2.31 (m, 1H).
