Reaction Steps

2-Aminoacetophenone hydrochloride (6.10 g, 35.5 mmol) was dissolved in dichloromethane (60 mL), and to the solution was added triethylamine (7.56 g, 74.9 mmol). The solution was cooled to 0° C., and to the solution was added methanesulfonyl chloride (2.84 mL, 36.5 mmol). The solution was stirred at the same temperature for 5 minutes, and then at room temperature for 2 hours. To the reaction mixture was added water and 1 mol/L hydrochloric acid, and the mixture was extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was suspended in chloroform (5 mL) and the suspension was stirred, and then, the resulted crystals were collected by filtration to give 2-(methylsulfonylamino)acetophenone (4.58 g, 57%).
