実験手順

A mixture of 3-(5-nitro-pyrid-2-yl)propenoic acid ethyl ester [0.8 g Reference Example 5(a)], ethanol (30 ml) and 5% palladium on charcoal (0.13 g) was stirred at ambient temperature under an atmosphere of hydrogen for 7 hours, left to stand over night and then stirred for a further 24 hours. The reaction mixture was filtered through a short pad of diatomaceous earth. The filtrate was evaporated to give the title compound (0.7 g) as a green oil.
