Komponenten

Versuchsvorschrift

To a stirring solution of 1,1′-thiocarbonyldipyridin-2(1H)-one (222 mg, 0.956 mmol) in dchloromethane (5 mL) was added a solution of 5,6,7,8-tetrahydroisoquinolin-3-amine (139 mg, 0.938 mmol) in dichloromethane (1.5 mL) and the resulting solution was stirred at room temperature overnight. The reaction mixture was applied directly to a Biotage column in 20-25% ethyl acetate/hexane, collecting the first major peak. Yield 141.8 mg (79%) 3-iothiocyanato-5,6,7,8-tetrahydroisoquinoline. NMR 1H NMR (500 MHz, CHLOROFORM-d) δ ppm 8.10 (1H, s), 6.84 (1H, s), 2.74 (4H, t, J=6.3 Hz), 1.81 (4H, dd, J=4.0, 2.7 Hz).
