Reaction Steps
To a stirred solution of 2-(bromomethyl)-3-nitrobenzonitrile (1.10 g, 4.56 mmol) and pyrrolidine (0.65 g, 9.13 mmol) in CH2Cl2 (15 mL) was added triethylamine (1.85 g, 18.25 mmol) dropwise at 0° C. The mixture was stirred at room temperature for 2 h and evaporated to dryness under reduced pressure. The residue was diluted with water (10 mL) and extracted with CH2Cl2 (3×50 mL). The CH2Cl2 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-2-(pyrrolidin-1-ylmethyl)benzonitrile (0.96 g, 91%) as a yellow solid. 1H NMR (400 MHz, CDCl3): δ 7.90 (d, 1 H, J=7.6 Hz), 7.83 (dd, 1H, J=7.6, 0.8 Hz), 7.52 (t, 1H, J=7.6 Hz), 4.14 (s, 2H), 2.52 (br s, 4H), 1.72 (br s, 4H).
