Abstract We report a novel synthesis of N??alkyl??N??alkyloxycarbonylaminomethyl (NANAOCAM) prodrugs of acetaminophen, theophylline, and 6??mercaptopurine by alkylation of the corresponding drug molecule with N??alkyl??N??alkyloxycarbonylaminomethyl chlorides in good yield. Most of the alkylating agents were efficiently synthesized by chloromethylation of N??alkyl carbamic acid alkyl esters, which in turn were made from ...
