실험 절차
To a suspension of but-3-yn-1-amine hydrochloride (200 mg, 1.89 mmol) and triethylamine (425 μL, 3.78 mmol) in DCM (60 mL) was added morpholine-4-carbonyl chloride (218 μL, 1.89 mmol). The reaction was stirred at RT overnight and then washed with aq hydrochloric acid (2 M, 2×20 mL), saturated aq sodium bicarbonate (2×20 mL), dried, filtered and evaporated in vacuo. The residue was purified by flash column chromatography, eluting with 0-100% ethyl acetate in heptane, to afford the title compound (13) (164 mg, 48%) as a white solid. 1H NMR (500 MHz, DMSO-d6) δ: 2.28 (2H, td), 2.82 (1H, t), 3.09-3.18 (2H, m), 3.20-3.27 (4H, m), 3.48-3.57 (4H, m), 6.74 (1H, t).
