1,8-Naphthyridines. Part II. Preparation and some reactions of 2-substituted derivatives
Abstract
Several new 2-substituted 1,8-naphthyridines have been prepared by the decarboxylation of their 3-carboxylic acids. 3-Bromomethyl-2-nitropyridine has been used in a new synthesis of 2-hydroxy-1,8-naphthyridine. Some chemical reactions, u.v., i.r., and n.m.r. spectra are reported.
