Mode opératoire

4-[1-Cyclohexyl-3-(5-methylsulfanyl-thiazol-2-yl)-ureido]-piperidine-1-carboxylic acid tert-butyl ester was prepared as described in general procedure (H) and (I) using 4-[1-cyclohexyl-3-(5-thiocyanato-thiazol-2-yl)-ureido]-piperidine-1-carboxylic acid tert-butyl ester, dithioerythritol and methyl iodide. Removal of the Boc group and N-acylation using thiophene-2 carboxylic acid as described in general procedure (G), steps 3 and 4 gave the title compound.
