실험 절차

A small vial was charged with 2 mL of acetonitrile, cesium carbonate (50 mg, 0.15 mmol), (R)-2-chloro-5-((1-(3-chlorophenyl)ethylamino)methyl)phenol 83 (30 mg, 0.10 mmol), and 3-(chloromethyl)-1-methylpiperidine (16 mg, 0.11 mmol). The vial was placed in a reaction block and it was heated to 85° C. and stirred for 14 h. The vial was allowed to cool to room temperature and the solution was filtered through a syringe filter into a well of a 24 well plate. This plate was concentrated down in a Genevac vacuum instrument. The plate was by preparatory HPLC. The desired fractions were combined and lyophilized. The final product, (1R)—N-(4-chloro-3-((1-methylpiperidin-3-yl)methoxy)benzyl)-1-(3-chlorophenyl)ethanamine 84 (32 mg, 75% yield) was isolated as a white solid of the TFA salt. 1H NMR (400 MHz, d4-methanol) δ ppm 1.44-1.56 (m, 1H) 1.72 (m, 2H) 1.99 (m, 1H) 2.07 (m, 1H) 2.40 (m, 1H) 2.91-3.00 (m, 4H) 3.55 (m, 1H) 3.67-3.74 (m, 1H) 3.93-4.01 (m, 2H) 4.10 (dd, J=9.00, 4.11 Hz, 1H) 4.18 (d, J=13.11 Hz, 1H) 4.48 (q, J=6.85 Hz, 1H) 5.50 (s, 1H) 7.00 (d, J=8.22, 1H) 7.15 (s, 1H) 7.43-7.52 (m, 3H) 7.57 (s, 1H). Mass spectrum: calculated for C22H28C12N2O 407.4. found 408.4 (M++1).
