Versuchsvorschrift

To 2-chloro-6-trifluoromethyl-nicotinonitrile (0.5 g, 2.4 mmol) in methanol (30 mL) was added sodium methylate in small portion (2 mol eq, 0.26 g). The reaction mixture was heated at 60° C. overnight. The solvent was distilled under reduced pressure and water was added to the residue. The aqueous solution was extracted with EtOAc (3×25 mL) and the organic phases were evaporated at reduced pressure to give 28c as a pale yellow oil (0.48 g, 2.33 mmol, 97% Yield). 1HNMR (DMSO, 200 MHz) δ 4.04 (s, 3H), 7.71 (d, 1H, J=6), 8.59 (d, 1H, J=6).
