To a solution of 6.85 gm (50 mmol) 4-methoxy-2-methylaniline in 70 ml of methylene chloride was introduced 8.5 gm (ml; mmol) pyridine followed by dropwise addition of 6.87 gm (60 mmol) methanesulfonylchloride. The reaction mixture was stirred at room temperature for 16 hours. The reaction mixture was washed with 1N HCl and then with saturated aqueous brine. The organics were dried with sodium sulfate and then evaporated in vacuo. The residue was triturated in diethyl ether to afford 7.5 gm (79%) of a light purple solid. Mass spectrum APCI (m/z) 216 (p+1).
