Bicyclo[2.2.1]heptane-1-methanesulfonic acid, 7,7-dimethyl-2-oxo-, (1S)- → HCID 53320012, compound

Participants

Reaction Steps

10-Camphorsulfonic acid (91 mg, 0.39 mmol) was added to 9-Ethyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamine (65 mg, 0.34 mmol) and 2-(2,5-Dichloro-pyrimidin-4-ylamino)-3-fluoro-N-methyl-benzamide (110 mg, 0.34 mmol) in Isopropyl alcohol (3 mL). The mixture was irradiated in a CEM microwave (130° C., 40 min). Complete conversion was achieved. The reaction was diluted with 5 mL satd. sodium bicarbonate and the ppt collected. The ppt was purified by ISCO (12 g SiO2, 0-100% EtOAc:Hex) to afford 2-[5-Chloro-2-(9-ethyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamino)-pyrimidin-4-ylamino]-3-fluoro-N-methyl-benzamide as a green foam (68 mg, 43%). LCMS: 471 (M+H), 1H-NMR (CDCl3): 8.64 (s, 1H), 8.03 (s, 1H), 7.29 (m, 3H), 7.10 (s, 1H), 6.88 (m, 1H), 6.68 (m, 2H), 6.07 (q, 1H, J=4.5 Hz), 4.03 (t, 2H, J=5.6 Hz), 3.17 (m, 4H), 2.91 (d, 3H, J=4.5 Hz), 1.99 (m, 2H), 1.16 (t, 3H, J=7.0 Hz); 19F-NMR: −112
