Reaction Steps

Into a microwave vial was combined 5-nitro-isochromen-1-one (1 g, 0.005 mol), 2-pyridinemethanamine (1 g, 0.009 mol), and methanol (20 mL, 0.5 mol). The mixture was heated at 150° C. for 2 hours. The mixture was cooled to room temperature. The usual work up of the reaction mixture gave a crude product which was then purified using a flash chromatography over silica gel to give the pure product as a yellow solid (0.7 g). MS m/z=282.4 (M+1).
