Reaction Steps

1.4g of 2-cyclopropylamino-4-methyl-thiazole-5-carboxylic acid was converted into 2-cyclopropylamino-4-methyl-thiazole-5-carboxylic acid chloride using 1.6g of phosphorus pentachloride according to the same procedure as EXAMPLE 1. Then 1.4g of amino-thiophen-3-yl-acetonitrile hydrochloride and 3.2ml of triethylamine were added thereto and the reaction mixture was treated according to the same procedure as EXAMPLE 1 to obtain 0.73g (Yield 35%) of the title compound.
