실험 절차

To a solution of Example 1 (0.20 g, 0.66 mmol) in DMF (5 mL) was added 2-picolyl chloride hydrochloride (0.10 g, 0.61 mmol) and triethylamine (0.24 mL, 1.72 mmol). The subsequent mixture was stirred at ambient temperature overnight. The reaction mixture was concentrated under reduced pressure. The crude residue was extracted into ethyl acetate (25 mL) and washed with water (25 mL) followed by brine (25 mL). The combined organic layers were dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The crude product was purified by flash chromatography using hexane/EtOAc (gradient system) to give the title compound (0.07 g, 36%); 1H NMR (400 MHz, CDCl3); δ 1.73-1.80 (m, 3H), 2.05 (m, 1H), 2.40 (m, 1H), 3.02-3.08 (m, 2H), 3.71 (d, J=13.6 Hz, 1H), 3.83 (m, 1H), 3.91 (s, 2H), 3.95 (m, 1H), 4.25 (d, J=13.6 Hz, 1H), 6.79 (d, J=8.8 Hz, 2H), 7.07 (d, J=8.8 Hz, 2H), 7.15-7.20 (m, 4H), 7.25-7.27 (m, 2H), 7.41 (m, 1H), 7.61 (m, 1H), 8.53 (m, 1H); MS (m/z) 359.2 (M+1); LC (100.0%).
