Versuchsvorschrift
Synthesized according to General Procedure A: 3-chlorobenzyl chloride (4{8}, 5 mL, 39.3 mmol, 1 equiv.), piperazine (20.3 g, 235.7 mmol, 6 equiv.), THF (85.4 mL). Purification with flash column chromatography on silica gel (4:1 EtOAc:MeOH) afforded 5{8} (5.41 g, 65%) as a light yellow liquid. 1H-NMR (400 MHz, CDCl3): δ 7.28 (br s, 1H) 7.19-7.12 (m, 3H), 3.39 (s, 2H), 2.82 (t, 4H, J=5.6 Hz), 2.34 (br s, 4H), 1.54 (br s, 1H). 13C-NMR (100 MHz, CDCl3): δ 140.2, 133.9, 129.2, 128.8, 127.0, 126.9, 62.8, 54.3, 45.9.
