실험 절차

To a solution of 5-cyclohex-1-enyl-3-[(trans-4-hydroxy-cyclohexyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (390 mg, 0.85 mmol) in dry DMF (3 mL) at 0° C. was added 0.34 mL of 10M solution of CHF2I in benzene, followed by NaH (60% suspension in oil, 68 mg, 1.70 mmol), and the mixture was stirred for 2 h allowing to warm up to room temperature. Then it has been transferred into a sealed tube and heated in a microwave oven for 20 min at 120° C. The mixture was treated as described in example 4, and purified by column chromatography on silica gel eluting with 0→50% ethyl acetate in hexane to give 5-cyclohex-1-enyl-3-[cyclohex-3-enyl-(trans-4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (132 mg, 35%).
