Amantadine → [2-(1-Adamantylamino)-2-oxoethoxy]acetic Acid

참여 물질

반응 단계

In a similar operation, a solution of 11.56 g (0.100 mole) of diglycolic anhydride in 1 liter of dichloromethane was added with stirring to a solution of 15.11 grams (0.100 mole) of 1-adamantanamine in 700 milliliters of dichloromethane during about 24 minutes at about 15° to 25° C., whereupon a reaction took place with the formation of heterogeneous milky white mixture. The mixture was stirred for 3.67 hours at temperatures of about 23°-25° C. to complete the reaction with the formation of the desired product in the reaction mixture. The mixture was then concentrated on a rotary evaporator to recover 32.7 grams of a white solid which after recrystallization from 1:1 isopropanol-water mixture yielded the desired [2-(1-adamantylamino)-2-oxoethoxy]acetic acid as white plates, m.p. 181°-183° C.
