Über Mannichbasen, 17. Mitt. Amino- und Amidoalkylierung von 2-Methylnaphthol bzw. 1-Naphthol

Mannich Bases, XVII: Amino- and Amidoalkylation of 2-Methylnaphthol and 1-Naphthol Under the usual conditions of aminoalkylation 2-methylnaphthol yields the Mannich bases or the methylene biscompound 4 depending on the basicity of the amine. With iminium salts, however, the hydrochlorides of the aminoalkyl derivatives are obtained. The amidoalkylation of 1-naphthol yields mono- or disubstituted products depending on the starting components.
