HATU (245 mg, 0.644 mmol) was added to a solution of 1-(2-{4-[(2-allyloxy-ethyl)-methyl-carbamoyl]-2-methyl-phenyl}-ethanesulfonyl)-4-amino-piperidine-4-carboxylic amide (250 mg), 3-but-3-enyloxy-4-trifluoromethyl-benzoic acid (155 mg, 0.596 mmol) and diisopropylethylamine (0.140 ml, 0.812 mmol) in DMF (5 ml), and the mixture was stirred at room temperature for 1.5 hours. Water was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine, and then dried over anhydrous sodium sulfate and concentrated under reduced pressure to give 1-(2-{4-[(2-allyloxy-ethyl)-methyl-carbamoyl]-2-methyl-phenyl}-ethanesulfonyl)-4-(3-but-3-enyloxy-4-trifluoromethyl-benzoylamino)-piperidine-4-carboxylic amide as a crude compound (381 mg).
