A suspension of Zn powder (620 mg, 9.48 mmol) and 1-(2-(2-chloro-4-nitrophenoxy)ethyl)pyrrolidine (320 mg, 1.19 mmol) in AcOH:H2O (3:1 mL) was heated at 55° C. for 2 h. After cooling the reaction to RT, any solid was removed by filtration and rinsed with AcOH and CH2Cl2. Once the combined filtrate was concentrated using a rotavap, the resulting residue was adjusted pH to 10 with NH4OH and extracted with CH2Cl2 (2×50 mL). The combined organic layers were washed with H2O (10 mL), then dried over MgSO4. After removal of the solvent under vacuum the pale brownish oil (0.26 g, 93%) was carried forward without further purification. MS (ESI) 241 (M+H)+.
