Reaction Steps

1.5g of 2-t-butylamino-4-methyl-thiazole-5-carboxylic acid was converted into 2-t-butylamino-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-2-yl-acetonitrile hydrochloride and 3.3ml of triethylamine were added thereto and the reaction mixture was treated according to the same procedure as EXAMPLE 1 to obtain 0.96g (Yield 41%) of the title compound.
