Reaction Conditions

Reaction Steps

To a solution of 424 (400 mg, 1.24 mmol) and DMF (2.0 mL) was added sodium azide (0.806 g, 12.4 mmol). The mixture was heated at 90° C. overnight. The mixture was cooled, diluted with H2O (30 mL) and extracted with EtOAc (3×50 mL). The combined extracts were washed with water (3×30 mL), dried (Na2SO4), filtered and concentrated in vacuo to afford 300 mg of trans-(±)-3-azido-4-(4-chloro-3-fluorophenoxy)-1-methylpyrrolidine (426) which was used for next step without further purification: LC-MS (ESI) m/z 271 (M+H).
