Participants

Reaction Steps

N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (490 mg, 1.4 mmol) in Acetone (5 mL), Cesium Carbonate (706 mg, 2.17 mmol)was added; after 15 min, Methyl iodide (95.0 uL, 1.53 mmol) was added and the mixture stirred at room temperature. After 4 h, a second aliquot of Methyl iodide (15 uL, 0.24 mmol) was added to drive the reaction to completion. After 30 min, the mixture was partitioned between 20 mL DCM/20 mL water, extracted 2×20 mL DCM. The combined organics were dried over sodium sulfate, filtered and con. in vacuo to afford N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-N-methyl-methanesulfonamide as an oil in quantitative yield. 1H-NMR (CDCl3): 8.02 (s, 1H), 5.94 (d, 1H, J=7.6 Hz), 4.11 (m, 1H), 3.74 (m, 1H), 2.84 (s, 3H), 2.80 (s, 3H), 2.35 (m, 1H), 1.84 (m, 3H), 1.71 (m, 1H), 1.42 (m, 2H), 1.27 (m, 1H).
