実験手順

Commercially available 4-oxo-4-(3-trifluoromethylphenyl)butyric acid (45.5 mg, 0.185 mmol) was dissolved in dry THF (3 mL). To the above solution was added triethyl amine (18.7 mg, 0.185 mmol) and isobutyl chloroformate (25.3 mg, 0.185 mmol) at 0° C. The mixture was stirred at 0° C. for 5 min. before the solution of (1R,3R,4S)-N1-isopropyl-N1-methyl-3-(phenylsulfonylmethyl)cyclohexane-1,4-diamine (see 30b) (50 mg, 0.154 mmol) in dry THF (3 mL) was added. The resulting mixture was warmed up to room temperature. The reaction was completed by 0.5 h. The mixture was treated with 1 N NaOH (5 mL) and extracted with CH2Cl2 (10 mL×2). The organic extracts were washed with water, brine and evaporated. The residue was chromatographed on silica gel (4% NH4OH/MeOH/CH2Cl2) to give the product (53 mg). MS found: (M+1)+: 553.32
