実験手順
A solution of 4-chloro-1-(5-ethoxycarbonylpyrid-2-yl)-2-methylimidazo[4,5-c]pyridine in ethanol (100 ml) was hydrogenated over 30% palladium on carbon (3 g) and magnesium oxide (0.8 g) at 50 p.s.i. (345 kPa) for 30 hours. The mixture was filtered through Arbocel filter aid and the filter cake washed with boiling ethanol (6×50 ml). The filtrate was concentrated under reduced pressure yielding the title compound as a white foam, (2.75 g, 96%).
