실험 절차
A solution of 11.63 grams (0.100 mole) of diglycolic anhydride in 1 liter of dichloromethane (prepared by heating the anhydride and dichloromethane on a steam bath) was added to a solution of 15.55 grams (0.100 mole) of propylhexedrine in 700 milliliters of dichloromethane at temperatures in the range of from about 21° to about 30° during an interval of about 10 minutes. After the addition, the mixture was stirred at a temperature range of 25° to 30° C. for about 40 minutes whereupon a reaction took place with the formation of a product in the reaction mixture. The mixture was then concentrated on a rotary evaporator to recover the {2-[(2-cyclohexyl-1-methylethyl)methylamino]-2-oxoethoxy}-acetic acid product as a partially crystalline residue which after recrystallization from an ethyl acetate-hexane mixture was in the form of white plates, m.p. 90°-91° C.
