실험 절차

To a solution of 3 g (10.30 mmol) of [(3S)-2-(tert-butoxycarbonyl)-1,2,3,4-tetrahydroisoquinolin-3-yl]acetic acid in 100 mL of dichloromethane, there are added dropwise 1.10 mL (11.32 mmol) of morpholine, still dropwise 4.3 mL (30.9 mmol) of triethylamine, 2.20 g (12.40 mmol) of EDC and 1.70 g (1.68 mmol) of HOBt (hydroxybenzotriazole). The batch is stirred at ambient temperature for 15 hours. The reaction mixture is then diluted with dichloromethane, successively washed with 1M HCl solution, saturated aqueous NaHCO3 solution and then brine until neutral. The organic phase is then dried over MgSO4, filtered and concentrated to dryness. After purification by chromatography over silica gel using dichloromethane and methanol as eluants, the title product is obtained in the form of an oil.
