Reaction Steps

To a solution of 5-(3,3-dimethyl-but-1-ynyl)-3-[(cis-4-methanesulfonyloxy-cyclohexyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (1.16 g, 2.00 mmol) in 10 ml of DMF is added sodium azide (0.65 g, 10 mmol). The reaction mixture is stirred for 48 h at 50° C. The mixture is diluted with ethyl acetate, washed 3 times with water and 1 time with brine. The organic layer is dried with sodium sulfate, filtered and concentrated under reduce pressure to give 3-[(trans-4-azido-cyclohexyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-5-(3,3-dimethyl-but-1-ynyl)-thiophene-2-carboxylic acid methyl ester.
