Procedure
N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (490 mg, 1.4 mmol) in Acetone (5 mL) was added Cesium Carbonate (706 mg, 2.17 mmol); after 15 min, Iodoethane (122 uL, 1.53 mmol) was added and the mixture stirred at room temperature 5d. Conc. in vacuo onto Celite and chromatography (0-20% EtOAc:Hex, ISCO silica gel) afforded N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-N-ethyl-methanesulfonamide as a clear oil (400 mg, 75%). 1H-NMR (CDCl3): 8.01 (s, 1H), 6.32 (d, 1H, J=6.8 Hz), 4.03 (m, 1H), 3.76 (m, 1H), 3.33 (m, 1H), 3.20 (m, 1H), 2.91 (s, 3H), 2.41 (m, 1H), 1.92 (m, 2H), 1.72 (m, 2H), 1.40 (m, 2H), 1.21 (m, 4H).
