실험 절차

A 18-mL vial was charged with [2-bromo-5-[[2-(5-chloro-2-thienyl)-5-ethyl-6-methyl-pyrimidin-4-yl]amino]phenyl]methanol (93 mg, 0.21 mmol), acetyl chloride (100 mg, 1.27 mmol, 6 eq.). Pyridine (1 ml) was added followed by 4-(dimethylamino)pyridine (5 mg, 0.2 eq.). The resulting mixture was stirred at rt for 2 hr. Then water was (5 ml) added. The precipitate was collected and washed with water. The crude product was purified by chromatography on silica gel using dichloromethane as eluent to give the tile compound (73 mg, 72% yield).
