Reaction Conditions

Reaction Steps

To a stirred solution of 4-fluoronitrobenzene (5.0 g, 35.43 mmol) in DMF (40 mL) were added morpholine (4.7 mL, 53.15 mmol) and cesium carbonate (17.3 g, 53.15 mmol). The reaction mixture was stirred at 60° C. for 48 h, then water (50 mL) was added. The solid formed was filtered and washed with water (5×100 mL), then Et2O (3×50 mL) to give the title compound (6.5 g, 88%) as a yellow solid that was used without further purification. δH (DMSO-d6) 8.12-8.02 (2H, m), 7.09-7.00 (2H, m), 3.79-3.68 (4H, m), 4.46-3.37 (4H, m). LCMS (ES+) 208.9 (M+H)+, RT 2.49 minutes (Method 3).
