Bicyclo[2.2.1]heptane-1-methanesulfonic acid, 7,7-dimethyl-2-oxo-, (1S)- → 3-{2-[5-Chloro-2-(5,5-dimethyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-8-ylamino)-pyrimidin-4-ylamino]-5-morpholin-4-yl-phenoxy}-propionitrile

Reaction Steps

3-[2-(2,5-Dichloro-pyrimidin-4-ylamino)-5-morpholin-4-yl-phenoxy]-propionitrile (88 mg, 0.22 mmol), 8-Amino-5,5-dimethyl-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (46 mg, 0.22 mmol), and 10-Camphorsulfonic acid (7.8 mg, 0.033 mmol) in Isopropyl alcohol (2 mL) was irradiated in a CEM microwave (140° C., 30 min). The mixture was diluted with 2 mL water and 0.25 mL satd. sodium bicarbonate, stirred for 10 min, then cooled for 1 h. The resultant solids were collected, washing with water, drying in vacuo to afford 3-{2-[5-Chloro-2-(5,5-dimethyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-8-ylamino)-pyrimidin-4-ylamino]-5-morpholin-4-yl-phenoxy}-propionitrile as dark yellow solids (94 mg, 75%). MP: 150-156° C., LCMS 562 (M+H), 1H-NMR (CDCl3): 8.00 (d, 1H, J=8.9 Hz), 7.98 (s, 1H), 7.55 (s, 1H), 7.30 (d, 1H, J=8.4 Hz), 7.04 (s, 1H), 6.96 (d, 1H, J=8.4 Hz), 6.61 (d, 1H, J=8.8 Hz), 6.52 (s, 1H), 4.27 (t, 2H, J=6.2 Hz), 3.90 (t, 4H, J=4.7 Hz), 3.23 (t, 4H, J=4.7 Hz), 2.87 (t, 2H, J=6.2 Hz), 2.38 (t, 2H, J=7.0 Hz), 2.09 (t, 2H, J=7.0 Hz).
