Reaction Steps
To a solution of ethyl 2-amino-5-(2-pyridyl)-4-thiazolecarboxylate (2.49 g) in ethyleneglycol (10 ml) were added N,N-dimethylethylenediamine (1.76 g) and 36% hydrochloric acid (0.5 ml) and the mixture was stirred at 80° C. for 2 hours. The reaction mixture was poured into water (50 ml), adjusted to pH 8 with aqueous potassium carbonate and extracted with chloroform. The extract was washed with brine, dried over magnesium sulfate and evaporated in vacuo. The residue was recrystallized from acetonitrile to give 2-amino-4-[N-[2-(N,N-dimethylamino)ethyl]carbamoyl]-5-(2-pyridyl)thiazole (2.0 g).
