Procedure
To a stirred solution of 3-(bromomethyl)-5-nitrobenzonitrile (1.50 g, 6.22 mmol) and morpholine (0.65 g, 7.46 mmol) in CH2Cl2 (15 mL) was added triethylamine (1.88 g, 18.66 mmol) dropwise at 0° C. The mixture was stirred at room temperature overnight and then evaporated to dryness under reduced pressure. 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-(morpholinomethyl)-5-nitrobenzonitrile (0.87 g, 85%) as an off-white solid. 1H NMR (400 MHz, CDCl3): δ 8.45 (br s, 1 H), 8.41 (br s, 1H), 8.01 (br s, 1H), 3.74 (br t, 4H, J=4.4 Hz), 3.64 (s, 2H), 2.48 (br t, 4H, J=4.4 Hz).
