Reaktionsschritte

In a similar operation, 5.0 grams (20 millimoles) of 4-benzhydrylpiperidine in 140 milliliters of dichloromethane was reacted with 2.3 grams (20 millimoles) of diglycolic anhydride in 200 milliliters of dichloromethan to obtain the desired [2-(4-benzhydrylpiperidino)-2-oxoethoxy]acetic acid product as a white solid which after purifying with ethyl acetate-hexane mixture had a m.p. of 139.5°-141° C.
