Reaction Steps

7a-(5-bromo-3-pyridinyl)-hexahydro-1H-pyrrolizine (107 mg, 0.52 mmol, from step 16c) was dissolved in methylene chloride, and Et2O saturated with HCl (g) was added. The solvent was removed, and the solid was crystallized from MeOH/Et2O and dried to afford the title compound as an off-white powder (118 mg). mp 192°-194° C. 1H NMR D2O, 300 MHz) δ2.13-2.51 (m, 6H), 2.57-2.66 (m, 2H), 3.36-3.44 (m, 2H), 3.81-3.89(m, 2H), 8.22 (s, 1H), 8.65 (s, 1H), 8.72 (s, 1H); MS (CI/NH3) m/z: 267/269 (M+H)+.
