Reaction Steps
3.93 g (0.033 mol) of dimethylformamide dimethyl acetal are added to a mixture of 7.38 g (0.03 mol) of [4-(2,6-dichloropyridin-4-yl)-thiazol-2-yl]-amine and 50 ml of methanol at 20° C., while stirring, and the mixture is stirred at 50° C. for a further 2 hours. Thereafter, the reaction mixture is cooled to 10° C. and filtered with suction. The residue is washed with 10 ml of cold methanol and then dried at 45° C. under reduced pressure. 7.5 g (83% of theory) of N-[4-(2,6-dichloropyridin-4-yl)-thiazol-2-yl]-N,N'-dimethylformamidine are obtained in this manner in the form of a solid substance of melting point 145° C.
