Procedure

To a solution of 2-amino-1-ethylbenzene (purchased from TCI, 12.1 g, 100 mmol) in pyridine (8.5 mL) and DCM (20 ml), methanesulfonyl chloride (7.74 ml, 11.4 g, 105 mmol) was added dropwise over 10 minutes at 0° C. The reaction mixture was stirred at room temperature for 1 hour. After cooling to 0° C., aluminum trichloride (33.3 g, 250 mmol) was added to the reaction mixture carefully. Then acetyl chloride (11 ml, 12 g, 150 mmol) was added dropwise over 15 minutes. The reaction mixture was diluted with toluene (50 ml) and poured into 2 M HCl aqueous solution (100 ml) with stirring at 0° C. The precipitates were filtered, washed with water and dried in vacuo to give the title compound (18 g, 75%) as yellow solids.
