Procedure

A mixture of 2-(diaminomethyleneamino)-4-(6-hydroxymethylpyridin-2-yl)thiazole (1.0 g) and thionyl chloride (10 ml) in a mixture of dichloromethane (10 ml) and tetrahydrofuran (10 ml) was stirred for 70 hours at ambient temperature. To the reaction mixture was added a diethyl ether (30 ml) and isolated precipitate was collected by filtration. The precipitate was added to a mixture of tetrahydrofuran, ethyl acetate and water and the mixture was adjusted to pH 9.5 with 20% aqueous potassium carbonate. The separated organic layer was washed with brine, dried over magnesium sulfate and evaporated to give 4-(6-chloromethylpyridin-2-yl)-2-(diaminomethyleneamino)thiazole (0.97 g).
