A 2.11 g quantity of 4-(3-ethoxy-2-hydroxypropoxy)aniline and 1.53 g of triethylamine were dissolved in 50 ml of dichloromethane. To the solution was added 1.71 g of 3-(methylsulfonyl)propionyl chloride with ice cooling. The same subsequent procedure as in Example 2 was repeated and recrystallization from benzene was performed, giving 3.25 g of N-[4-(3-ethoxy-2-hydroxypropoxy)phenyl]-3-(methylsulfonyl)propionamide in a yield of 94.2 %. M.p. 111° to 112° C.
