Reaction Steps

1.7g of 2-cyclopropylamino-4-methyl-thiazole-5-carboxylic acid was converted into 2-cyclopropylamino-4-methyl-thiazole-5-carboxylic acid chloride using 1.9g of phosphorus pentachloride according to the same procedure as EXAMPLE 1. Then 1.7g of amino-thiophen-2-yl-acetonitrile hydrochloride and 3.9ml of triethylamine were added thereto and the reaction mixture was treated according to the same procedure as EXAMPLE 1 to obtain 1.0g (Yield 39%) of the title compound.
