Versuchsvorschrift
The same procedure as described for compound 16 was applied to starting material 15 (2.4 g, 5.89 mmol), 4-benzylpiperidine (2.06 g, 11.78 mmol) and K2CO3 (0.814 g, 5.89 mmol). Purification was carried out on a silica gel TLC plate that was developed in with a 3% methanolic NH3 (7 M NH3 in methanol/97% CH2Cl2. The product was isolated as pale yellow oil (58%). 1H NMR (CDCl3) δ 7.328 (dd, 1H, Ar), 7.211 (t, 2H, Ar), 7.132 (t, 1H, Ar), 7.077 (m, 3H, Ar), 6.951 (m, 2H, Ar), 3.576 (s, 2H, —CH2—), 3.302 (d, 2H, —CH2—), 3.112 (m, 2H, —CH2—), 2.729 (m, 2H, —CH2—), 2.525 (m, 6H), 2.395 (m, 2H, —CH2—), 1.819 (m, 2H, —CH2—), 1.724 (m, 5H), 1.424 (m, 2H, —CH2—), 1.356 (s, 9H, —C(CH3)3), 1.325 (s, 9H, —C(CH3)3), 1.224 (s(br), 4H, —CH2—CH2—). Mass Spec.=579.86 (M+H)+.
