Procedure

To a solution of 5-(3,3-dimethyl-but-1-ynyl)-3-(4-[1,2,3]triazol-1-yl-cyclohexylamino)-thiophene-2-carboxylic acid methyl ester (0.20 g, 0.50 mmol) in toluene (1 ml) is added a solution of trans-4-methylcyclohexyl carboxylic acid chloride 1 M (1.0 ml, 1.0 mmol) and pyridine (0.046 ml, 0.58 mmol). The mixture is stirred overnight at 105° C. and diluted with ethyl acetate. The organic layer is washed with NaHCO3 sat (2×) and brine. The organic layer is dried with sodium sulfate, filtered and concentrated under reduce pressure. The residue is purified by silica gel column chromatography (20% ethyl acetate/hexane to 100% ethyl acetate followed by 10% MeOH/ethyl acetate) to give 5-(3,3-dimethyl-but-1-ynyl)-3-[(trans-4-methyl-cyclohexanecarbonyl)-(4-[1,2,3]triazol-1-yl-cyclohexyl)-amino]-thiophene-2-carboxylic acid methyl ester.
