실험 절차

(1S)-2-(1-Cyclohexylpiperidin-4-yl)-1-methyl-3-oxo-2,3-dihydro-1H-isoindole-4-carboxylic acid (0.15 gr, 0.42 mmol), hydroxybenzotriazole ammonium salt (0.13 gr, 0.84 mmol) and 1-ethyl-3-(3′-dimethylamino) carbodiimide hydrochloric acid salt (0.16 gr, 0.84 mmol) were dissolved in a mixture of tetrahydrofuran (6 mL) and triethylamine (0.23 mL, 1.68 mmol) and stirred under nitrogen atmosphere for 16 hours. Volatiles were evaporated and the crude was dissolved in dichloromethane and washed with 15% ammonium hydroxide. The organic phase was dried over anhydrous sodium sulfate and concentrated in vacuo. The crude was purified by flash chromatography (dichloromethane/methanol/7N ammonia in methanol 100:3:1) to afford the title compound (0.060 g, 40%) as a white solid.
