Procedure

N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (60.0 mg, 0.177 mmol), 2-Amino-3-methoxy-5-methyl-8,9-dihydro-5H-7-oxa-5-aza-benzocyclohepten-6-one (39.3 mg, 0.177 mmol) and 5 drops of HCl/dioxane were stirred in isopropyl alcohol (2.00 mL, 26.1 mmol) at 120° C. in a sealed tube. After 24 hours the reaction mixture was concentrated and then extracted with DCM (20 mL) and washed with sat. NaHCO3 (20 mL) followed by water. The organic layer was dried over MgSO4, filtered and concentrated. The residue was chromatographed on ISCO flash system (0-10% DCM:MeOH) to obtain one peak by LC/MS. When analyzed by HPLC, two peaks were shown. The fractions were concentrated and the residue was chromatographed on ISCO flash system (0-100% Hex:EtOAc) to obtain the product and the decarboxylated side product. The product was isolated as a pale blue solid (35.0 mg, 37.7%). mp: 160-162° C., MS (ESI+): 525 (M+H), 1H-NMR (CDCl3, 400 MHz) δ 8.11 (s, 1H), 7.95 (s, 1H), 7.68 (s, 1H), 7.15 (d, 1H), 7.01 (s, 1H), 6.85 (d, 1H), 4.36 (m, 2H), 3.88 (s, 3H), 3.30 (s, 3H), 2.90 (br s, 5H), 1.99 (br s, 3H), 1.7 (d, 2H), 1.5-1.1 (m, 5H).
