The 2-chloro-6-methyl-nicotinonitrile (0.8 g, 5.2 mmol) was added in small portion to a mixture of NaH 60% (4 mol eq, 0.8 g) in isopropanol (30 mL). The reaction mixture was heated at 50° C. overnight. The solvent was distilled and water was added to the residue. The aqueous solution was extracted with EtOAc (3×30 mL) and the organic phases were evaporated at reduced pressure to give 32a as a pale yellow deliquescent solid (1.25 g, quantitative yield). 1HNMR (DMSO, 200 MHz) δ 1.24 (s, 3H), 1.32 (s, 3H), 2.25 (s, 3H), 5.02 (m, 1H), 7.31 (d, 1H), 7.69 (m, 1H).
