Bicyclo[2.2.1]heptane-1-methanesulfonic acid, 7,7-dimethyl-2-oxo-, (1S)- → 3-[5-Chloro-2-(9-ethyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-2-ylamino)-pyrimidin-4-ylamino]-thiophene-2-carboxylic acid methylamide

Reaction Steps

9-Ethyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-2-ylamine (57 mg, 0.30 mmol), 10-Camphorsulfonic acid (72.3 mg, 0.311 mmol) and 3-(2,5-Dichloro-pyrimidin-4-ylamino)-thiophene-2-carboxylic acid methylamide (9.0E1 mg, 0.30 mmol) in Isopropyl alcohol (2.0 mL) was irradiated in a CEM microwave (120° C., 30 min). The mixture was diluted with satd. sodium bicarbonate (1 mL) and water (6 mL). The flocculent solids were separated from an oily residue on the sides of the vial, filtered and washed with water. Drying in vacuo of the solids furnished 3-[5-Chloro-2-(9-ethyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-2-ylamino)-pyrimidin-4-ylamino]-thiophene-2-carboxylic acid methylamide (67 mg, 49%). MP=153-155° C.; LCMS: 459 (M+H); 1H-NMR (CDCl3): 11.27 (s, 1H), 8.31 (d, 1H, J=5.1 Hz), 8.08 (s, 1H), 6.92 (s, 1H), 6.88 (m, 2H), 6.71 (s, 1H), 5.67 (s, 1H), 4.14 (m, 2H), 3.29 (m, 2H), 3.27 (m, 2H), 3.02 (d, 3H, J=4.8 Hz), 2.03 (m, 2H), 1.18 (t, 3H, J=6.4 Hz).
