Reaction Steps

To a solution of 5-cyclohex-1-enyl-3-[(trans-4-methylcyclohexanecarbonyl)-piperidin-4-yl-amino]-thiophene-2-carboxylic acid methyl ester (100 mg, 0.23 mmol) in dichloromethane (3 mL) was added triethylamine (3 mL) and isobutyryl chloride (28 μL, 0.27 mmol). The reaction mixture was stirred at room temperature for 12 h and then quenched with a saturated solution of NaHCO3. The organic layer was separated, dried (Na2SO4) and concentrated. The residue was purified by silica gel column chromatography using ethyl acetate and hexane (1:1) as eluent to obtain 5-cyclohex-1-enyl-3-[(1-isobutyryl-piperidin-4-yl)-(trans-4-methyl cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (55 mg, 47%) as a white solid.
