To a stirred solution of 2-chloro-4-fluoro-5-nitrotoluene (2.080 g, 10.97 mmol, as prepared above) in DMF (11.0 mL) at 70° C., was added dropwise, a solution of sodium glycinate (1.065 g, 10.97 mmol, Aldrich, used as received) in water (11.0 mL). The resulting suspension was stirred overnight at 70° C., cooled to room temperature, and the resulting red solid was filtered, washed with acetone (35 mL), and dried under vacuum to give 1.005 g (37%) of the pure (1H NMR) title compound as a red powder; 1H NMR (DMSO-d6): δ 2.184 (s, 3H), 3.396 (d, 2H, J=4.2 Hz), 6.852 (s, 1H), 7.991 (s, 1H), 8.671 (s, 1H).
