الإجراء التجريبي

4-[[2-carboxy-5-(3,3-dimethyl-but-1-ynyl)-thiophen-3-yl]-(4-methyl-cyclohexanecarbonyl)-amino]-piperidine-1-carboxylic acid hexahydro-furo[2,3-b]furan-3-(R)-yl ester was prepared in a similar fashion to 5-(3,3-dimethyl-but-1-ynyl)-3-{(4-trans-methyl-cyclohexanecarbonyl)-[4-(tetrahydro-pyran-4-yloxycarbonylamino)-cyclohexyl]-amino}-thiophene-2-carboxylic acid using method B, except the HCl salt of 5-(3,3-dimethyl-but-1-ynyl)-3-[(4-methyl-cyclohexanecarbonyl)-piperidin-4-yl-amino]-thiophene-2-carboxylic acid methyl ester was used instead of 3-[(4-amino-cyclohexyl)-(4-trans-methyl-cyclohexanecarbonyl)-amino]-5-(3,3-dimethyl-but-1-ynyl)-thiophene-2-carboxylic acid methyl ester, and 4-nitro-benzoic acid hexahydro-furo[2,3-b]furan-3-(R)-yl ester was used in place of the chloroformate of tetrahydro-pyran-4-ol.
