Versuchsvorschrift
Synthesized according to General Procedure A: 2-(bromomethyl)naphthalene (4{25}, 5 g, 22.6 mmol, 1 equiv.), piperazine (11.7 g, 135.7 mmol, 6 equiv.), THF (49.4 mL). Purification with flash column chromatography on silica gel (4:1 EtOAc:MeOH) afforded 5{25} (4.67 g, 91%) as a beige solid. 1H-NMR (500 MHz, CDCl3): δ 7.82-7.79 (m, 3H), 7.74 (s, 1H) 7.50 (dd, 1H, J=1.5, 8.5 Hz), 7.48-7.42 (m, 2H), 3.64 (s, 2H), 2.88 (t, 4H, J=5.0 Hz), 2.45 (br s, 4H), 1.52 (br s, 1H). 13C-NMR (125 MHz, CDCl3): δ 135.6, 133.2, 132.6, 127.7, 127.5, 127.5, 127.5, 127.4, 125.8, 125.4, 63.7, 54.5, 46.0.
