Procedure

Glacial acetic acid (25 mL) was added slowly to a mixture of zinc dust (2.76 g) and 4-(4,6-dimethyl-5-nitro-pyridin-2-yl)-morpholine (2.01 g) in tetrahydrofuran (100 mL) cooled to 0° C. The reaction mixture was then stirred for 16 hours at 25° C., filtered through celite, made basic with 25% aqueous ammonia and extracted with tetrahydrofuran (3×75 mL). The combined organic phases were dried over magnesium sulfate and concentrated in vacuo to furnish 1.76 g (100%) of the title compound as a dark red solid. GC-MS (m/z) 207 (M+); tR=7.27. 1H NMR (500 MHz, DMSO-d6): 2.07 (s, 3H), 2.20 (s, 3H), 3.16 (m, 4H), 3.67 (m, 4H), 4.10 (b, 2H), 6.38 (s, 1H).
