Versuchsvorschrift

22.8 g of p-acetamidophenyl chloroacetate were added in small portions to a solution of 7.5 g of diethylamine in 30 c.c. of triethylamine with stirring, while the temperature was maintained at between 40° C. and 50° C. with a bath of cold water if necessary. The process described in Example 1 was then followed to obtain 12 g of p-acetamidophenyl diethylaminoacetate hydrochloride melting point = 228° C.
