Краткое описание
By application of the Kress procedure for bromination it has been found that from the hydro-bromide of 1,7-naphthyridine with 1.1 equivalents of bromine in nitrobenzene a mixture of 3-and 5-bromo- and 3,5-dibromo-1,7-naphthyridine is obtained in reasonable yield. With an excess of bromine 3,5-dibromo-1,7-naphthyridine is nearly exclusively formed. Similar brominations of the hydrobromide of 1,8-naphthyridine with 1.1 equivalents of bromine gave 3-bromo- and 3,6-dibromo-1,8-naphthyridine. By using an excess of bromine a high-yield conversion into 3,6-dibromo-1,8-naphthyridine is observed. Bromination of the hydrochloride salt of 1,7- and 1,8-naphthyridine affords the same bromo derivatives.
