Temperature100 °C

Reaction Steps

The mixture of 1-fluoro-3-nitrobenzene (420 mg, 3 mmol) in DMF (1.5 mL), N-(2-aminoethyl)-pyrrolidine (514 mg, 4.5 mmol) and Cs2CO3 (977 mg, 3 mmol) is heated at 100° C. under microwave radiation for 2.5 hours, then concentrated. The mixture is diluted with EtOAc, washed with saturated NaHCO3 aqueous solution and brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The crude product is purified by column chromatography (SiO2, MeOH:CH2Cl2=1:99 to 10:90) to give 130 mg of the title compound as a light brown oil.
