Reaction Steps

To a solution of phenethylamine (2.42 g, 20 mmol) and NaOH (0.88 g, 22 mmol) in DCM/H2O (20 mL/20 mL) was added 4-chloro-butyryl chloride (2.82 g, 20 mmol) at 0° C. The resulting mixture was stirred at 0° C. for 20 min. The mixture was partitioned between DCM (20 mL) and H2O (10 mL). The organic layer was separated and washed with brine (10 mL), dried over anhydrous Na2SO4, filtered and concentrated to give a white solid. This residue was purified with silica gel column (Hexane/EtOAc=3/1 to 1/1) to obtain HJC-1-48 (4.2 g, 93%) as a white solid. 1H NMR (600 MHz, CDCl3) δ 7.32 (t, 2H, J=7.8 Hz), 7.23-7.26 (m, 1H), 7.20 (d, 2H, J=7.8 Hz), 5.46-5.47 (m, 1H), 3.52-3.58 (m, 4H), 2.82 (t, 2H, J=7.2 Hz), 2.31 (t, 2H, J=7.2 Hz), 2.07-2.11 (m, 2H).
