Reaction Steps
2-hydroxy-N-1,3-thiazol-2-ylbenzamide (502, 267.1 mg, 1.21 mmol) was placed into a 10 mL round bottom flask equipped with a stirbar and a septum with a dry nitrogen inlet. Dichloromethane (5.0 mL) and triethylamine (500 μL, 3.59 mmol) were added to form a light pink solution. Methanesulfonyl chloride (100 μL, 1.3 mmol) in dichloromethane (ca. 1.0 mL) was added dropwise to the stirring solution over ca. 30 seconds, and the reaction was stirred at room temperature for ca. 20 minutes before being quenched into saturated NaHCO3, and extracted with dichloromethane. The combined organics were washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. The crude product was recrystallized from hexanes/ethyl acetate to yield (284 mg, 78%) of 11 as a colorless crystalline solid. Example 11 (2-thiazol-2-ylcarbamoyl)phenyl methanesulfonate) has the empirical formula C11H10N2O4S and a molecular weight of 298.34.
