Methods of using prodrugs of GABA analogs and pharmaceutical compositions thereof to treat vulvodynia in a patient, and pharmaceutical compositions of prodrugs of GABA analogs useful in treating vulvodynia are disclosed.
Allyl 1 [(α-isobutanoyloxyethoxy)carbonyl]aminomethyl}-1-cyclohexane acetate can be prepared by combining allyl 1-aminomethyl-1-cyclohexane acetate hydrochloride, a polar organic solvent, chloroethyl chloroformate, and an amine base or an inorganic base selected from a group consisting of carbonate and bicarbonate to provide a reaction mixture; and adding isobutyric acid to the reaction mixture. The product can be purified and/or converted to gabapentin enacarbil.
