A mixture of 125 g. (0.73 mol) of O-chlorophenylacetic acid, 155 g. (1.3 mol) of thionyl chloride and 2-3 drops of dimethylformamide in 1500 ml. of toluene was stirred at room temperature for three hours. The toluene was evaporated under reduced pressure to give an oil which was dissolved in 200 ml. of methylene chloride. This was added dropwise to a solution of 165 g. (2.2 mol) of N-methylamino ethanol in 1 liter of methylene chloride. After addition was complete, the solution was stirred at room temperature for three hours. The organic solution was washed with water, dilute hydrochloric acid and saturated sodium chloride, dried over magnesium sulfate, filtered and evaporated to give 2-chloro-N-(2-hydroxyethyl)-N-methylbenzene acetamide as a crystalline solid, m.p. 77°.
