Reaktionsschritte
This compound was prepared via the general DCC/pyr coupling procedure from 8 (0.5138 g, 2.061 mmol), 4-methylsulfonylphenylacetic acid (0.8825 g, 4.119 mmol), DCC(0.8771 g, 4.251 mmol), and pyridine (0.34 mL, 4.245 mmol). The crude product was gravity column chromatographed eluting with CHCl3:2% NH3 before it was converted to the HCl salt with 1.0 M HCl in Et2O and crystallized from MeOH to yield 14 HCl.(0.4695 g, 47%): m.p. (HCl salt) 276-277° C.; 1H NMR (HCl salt, DMSO-d6) δ2.0 (br s, 4H, —CH2CH2—), 2.92 (s, 3H, —NCH3), 3.2 (s, 3H, —SO2CH3), 3.2-4.3 (complex, 8H, 4 —CH2—), 6.25 (m, 1H, —CH—), 7.61 (d, J=7.2 Hz, 2H, aromatic), 7.75 (m, 2H, aromatic), 7.89 (d, J=7 Hz, 2H, aromatic), 8.12 (s, 1H, aromatic), 8.25 (m, 1H, aromatic). MS(FAB) m/z 446. Anal. (C, H, N) C22H27N3O5S HCl.
