Reaction Conditions

Reaction Steps

To a solution of N,N-dimethylethylenediamine (0.59 ml) in pyridine (10 ml) were added phosphorus trichloride (1.3 g) and 2-amino-5-(4-pyridyl)-4-thiazolecarboxylic acid (1.5 g) and the mixture was stirred at 100° C. for 5 hours. The reaction mixture was poured into water (50 ml), adjusted to pH 8 with aqueous potassium carbonate and extracted with a mixture of chloroform and tetrahydrofuran. The extract was dried over magnesium sulfate and evaporated in vacuo to give 2-amino-4-[N-[2-(N,N-dimethylamino)ethyl]carbamoyl]-5-(4-pyridyl)thiazole (0.4 g).
