実験手順
A stirred solution of 3-nitro-2-p-tolylpyridine (5.0 g) in ethanol (200 ml) and concentrated hydrochloric acid (15 ml) was hydrogenated over pre-reduced platinum oxide (1.5 g) at 23°1 atm until hydrogen uptake was complete (~3 lh). The mixture was filtered through hyflo washing the pad of hyflo with water then the filtrate was evaporated in vacuo. Recrystallisation from isopropanol water gave a cream solid. The solid was treated with 2N sodium hydroxide solution and extracted with dichloromethane (5×200 ml). The combined organic extracts were dried (Na2SO4) and evaporated in vacuo to give the title compound as an orange-brown oil which partially crystallised on standing (2.20 g).
