Summary 1. N-Hydroxymethylphthalimide reacts with certain nitriles in concentrated sulfuric acid to yield the N-(phthalimido methyl) derivatives of the amides corresponding to the nitriles. It seems probable that the similar condensation of English and Clapp yielded a product analogous to those reported here. 3. N-Hydroxymethylphthalimide does not react with the active methylene group of malonic acid or ester in sulfuric acid solution.
