Reaktionsschritte

Dipyridin-2-ylmethanone oxime (500 mg, 2.510 mmol) and ammonium acetate were solubilized in ethanol and the mixture was reflux for 3 hours adding portion of zinc at 0 h, 1 h and 2 h. The reaction mixture was cooled down to room temperature and stirred over night. The pH was adjusted to 12 with sodium hydroxide and the mixture was filtered through celite. The mixture was diluted with ethyl acetate and the organic layer was washed with brine, dried over magnesium sulfate, filtered and evaporated to afford title compound 405 (282 mg, 61%) as a light yellow oil. MS (m/z): 186.2 (M+H). 1H NMR (CDCl3) δ (ppm): 8.50-8.49 (m, 2H), 7.56 (td, J=7.7, 1.8 Hz, 2H), 7.33 (dt, J=8.0, 0.9 Hz, 2H), 7.08 (ddd, J=7.4, 4.9, 1.2 Hz, 2H), 5.26 (s, 1H), 2.38 (s, 2H).
