AbstractAbstract
[en] The base-catalysed exchange of a proton of the methyl groups in acetanilides can be used to incorporate deuterium into these amides. 4'-Hydroxyl-2[2H]acetanilide (acetaminophen, paracetamol) can be prepared by the demethylation with boron tribromide of 4'-methoxy-2[2H] acetamide obtained by this base-catalysed exchange.
