Introduction of a new synthetic route about Isonicotinimidamide hydrochloride

The synthetic route of 6345-27-3 has been constantly updated, and we look forward to future research findings.

Reference of 6345-27-3 , The common heterocyclic compound, 6345-27-3, name is Isonicotinimidamide hydrochloride, molecular formula is C6H8ClN3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

General procedure: A 20 mL of Schlenk tube equipped with a stir bar was charged with benzyl bromides (0.12 mmol), aryl amidines (0.1 mmol), S8 (0.1 mmol), LiOtBu (0.4 mmol). The tube was sealed with a Teflon lined cap, and the reaction mixture was stirred at 140 ¡ãC for 12 h in oil bath. Then the solvent was concentrated in vacuum and the residue was purified by flash column chromatography on silica gel with petroleum ether-EtOAc as the eluent to give the desired product.

The synthetic route of 6345-27-3 has been constantly updated, and we look forward to future research findings.
