実験手順

4-Methyl-cyclohex-3-enecarbonyl chloride was prepared according to the procedure reported in Journal of Organic Chemistry (1986) 51(23), PP4485-8. This 4-Methyl-cyclohex-3-enecarbonyl chloride (0.121 g, 0.77 mmol) was dissolved along with 5-(4-Fluoro-phenyl)-3-isopropylamino-thiophene-2-carboxylic acid methyl ester (0.150 g, 0.51 mmol) in anhydrous 1,2-dichloroethane (2 mL). The reaction mixture was stirred for 16 h at reflux. Then, the solvents were removed and the residue was purified by flash chromatography (8:2 Hexane/EtOAc) to obtain 140 mg (66%) of 5-(4-Fluoro-phenyl)-3-[isopropyl-(4-methyl-cyclohex-3-enecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester. 1H NMR (CDCl3, 400 MHz): δ 7.60 (m, 2H), 7.15 (m, 2H), 7.02 (d, 1H), 5.42-5.20 (m, 1H), 4.99 (m, 1H), 3.83 (d, 3H), 2.41-1.50 (m, 10H), 1.20 (m, 3H), 0.98 (d, 3H).
