Reaction Steps
A mixture of N-(2-bromo-4-(1-methylethyl)phenyl)-N-ethyl-4-(1-hydroxyethyl)-6-methylpyrimidinamine (1.1 g, 2.7 mmol), triethylamine (1.5 mL, 11 mmol) and dichloromethane (15 mL) was stirred at 0° C. under a nitrogen atmosphere. Methanesulfonylchloride (364 mg, 3.2 mmol) was added dropwise and the reaction mixture was then stirred for 1.5 h. The resulting turbid solution was washed successively with an ice-cold 1 N HCl solution, a saturated NaHCO3 solution and a saturated NaCl solution. Drying over MgSO4, filtration and removal of solvent in vacuo gave N-(2-bromo-4-(1-methylethyl)phenyl)-N-ethyl-4-(1-methanesulfonyloxyethyl)-6-methylpyrimidinamine as a clear colorless oil (1.0 g): NMR (CDCl3, 300 MHz): 7.5 (d, 1H, J=1), 7.25-7.1 (m, 2H), 6.55 (s, 1H), 4.3-4.05 (m, 1H), 3.85-3.6 (m, 1H), 3.0-2.5 (m, 4H), 2.5-2.05 (br m, 3H), 1.3 (d, 6H, J=8), 1.2 (t, 3H, J=8); CI-MS, 456, 458 (M+H).
