実験手順
A solution of tert-butyl 3,3′-bipyridine-6-carboxylate (3.2 g, 12.5 mmol) in 4 M HCl in dioxane (100 ml) was stirred at 110° C. overnight. The reaction mixture was evaporated completely under reduced pressure and triturated twice from diethyl ether. Yield 3.2 g. 1H-NMR (400 MHz; D2O): δ 8.23-8.27 (m, 1H), 8.50 (d, 1H), 8.84 (d, 1H), 8.93 (d, 1H), 8.98 (d, 1H), 9.16 (s, 1H), 9.26 (s, 1H).
