Reaction Steps

To a solution of N-(4-{[4-(2-hydroxyethyl)phenoxy]methyl}-1,3-thiazol-2-yl)acetamide (310.0 mg, 1.060 mmol) in anhydrous dichloromethane (8 ml) were added triethylamine (0.27 ml, 1.91 mmol) and 4-dimethylaminopyridine (13.0 mg, 0.106 mmol), and the mixture was cooled to 0° C. Methanesulfonyl chloride (0.12 ml, 1.60 mmol) was added dropwise at 0° C. The mixture was warmed to room temperature and stirred for 1 hr. Iced water (20 ml) was added to the reaction mixture and the mixture was stirred for 20 min, extracted 3 times with ethyl acetate. The combined organic layer was washed with 1M hydrochloric acid, saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give 2-(4-{[2-(acetylamino)-1,3-thiazol-4-yl]methoxy}phenyl)ethyl methanesulfonate (410.8 mg, containing N-(4-{[4-(2-chloroethyl)phenoxy]methyl}-1,3-thiazol-2-yl)acetamide) as an orange solid.
