Reaction Steps
To a solution of 4-(6-chloro-4-methoxy-5-nitropyridin-2-yl)-morpholine (0.38 g) in concentrated hydrochloric acid (20 mL) was added a solution of stannous dichloride (1.57 g) in concentrated hydrochloric acid (60 mL). The reaction mixture was heated to 75° C. for 5 minutes and then poured on to chrushed ice (100 g) and extracted with ethyl acetate (2×20 mL). The combined organic phases were dried over magnesium sulfate and concentrated in vacuo, to furnish 0.28 g (83% yield) of the title compound as an off-white solid. 1H NMR (500 MHz, CDCl3): 3.35 (m, 4H), 3.65 (br s, 2H), 3.80 (m, 4H), 3.90 (s, 3H), 6.10 (s, 1H).
