[Cl:1][C:2]1[CH:3]=[C:4]([CH2:9][OH:10])[CH:5]=[N:6][C:7]=1Cl.[CH3:11][O-:12].[Na+]>CO>[Cl:1][C:2]1[CH:3]=[C:4]([CH2:9][OH:10])[CH:5]=[N:6][C:7]=1[O:12][CH3:11](5,6-Dichloro-pyridin-3-yl)-methanol was dissolved in a saturated solution of NaOMe in MeOH and heated to reflux overnight. Evaporation of MeOH, work-up (EtOAc) and evaporation gave the title compound. 1H-NMR (CDCl3) δ 8.03 (d, 1H), 7.72 (d, 1H), 4.65 (s, 2H), 4.04 (s, 3H).
