Procedure

Preparation according to Example 2. (+3-(3-chloro-2-fluorophenyl)-3-methoxypyrrolidine (0.234 g, 1.02 mmol), tetrahydrofuran (20 ml), iodoethane (0.122 ml, 1.15 mmol) and triethylamine (0.285 ml, 2.04 mmol), the solution was stirred for 26 h. Purification by HPLC on waters OBD C18, 5 μm (MeOH/33 mM NH3, 20:80 to 65:35) gave the title compound 0.094 g (35.9%). [a]D=−16.1° (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+, 4), 242 (38), 227 (20), 157 (31), 71 (bp).
