Reaction Steps

To a stirred solution of 3-(bromomethyl)-5-nitrobenzonitrile (1.50 g, 6.22 mmol) and pyrrolidine (0.53 g, 7.46 mmol) in CH2Cl2 (15 mL) was added triethylamine (1.88 g, 18.68 mmol) dropwise at 0° C., and the mixture was stirred at room temperature overnight. The reaction mixture was evaporated to dryness under reduced pressure, and the residue was diluted with water (15 mL) and extracted with EtOAc (3×50 mL). The EtOAc solution was dried over anhydrous Na2SO4, filtered, and evaporated to dryness under reduced pressure. The residue was purified by MPLC on silica gel using a mixture of EtOAc and hexane as eluent to give 3-nitro-5-(pyrrolidin-1-ylmethyl)benzonitrile (1.30 g, 90%) as a yellow solid. 1H NMR (400 MHz, CDCl3): δ 8.45 (br s, 1H), 8.39 (br t, 1H, J=1.6 Hz), 8.02 (br s, 1H), 3.78 (s, 2H), 2.56 (br s, 4H), 1.84 (br s, 4H).
