As described for example 135a, 2-chloro-thiazole-5-carboxylic acid ethyl ester (500 mg, 2.6 mmol) was converted, using 4-aminotetrahydropyran instead of isopropylamine, to the title compound (471 mg, 73%) which was obtained as a white solid after purification by chromatography (silica, 0 to 3% methanol in dichloromethane). MS: m/e=247.3 [M+H]+.
