Reaction Steps

To a solution of (+)-3-(3-chloro-2-fluorophenyl)-3-methoxypyrrolidine (0.25 g, 1.08 mmol) and triethylamine (0.305 ml, 2.17 mmol) in tetrahydrofuran (20 ml), was added iodoethane (0.13 ml, 1.63 mmol) and the solution was stirred at ambient temperature for 26 h. Water (20 ml) was added and the aqueous phase was extracted with EtOAc (2×50 ml), the combined organic phase was dried (Na2SO4) and the solvent was evaporated. Purification by HPLC on waters OBD C18, 5 μm (MeOH/33 mM NH3, 20:80 to 65:35) gave the title compound 0.106 g (38%). [a]D=+16.5° (methanol). The amine was converted to the fumaric acid salt and recrystallized from 2-propanol/diisopropyl ether: M.p. 131-133° C. MS m/z (rel. intensity, 70 eV) 257 (M+, 9), 242 (bp), 227 (44), 157 (44), 71 (89).
