Versuchsvorschrift

A mixture of 2-methoxy-4-methyl-5-nitropyridine 4-Methyl-5-nitro-2-pyrrolidin-1-ylpyridine (1.68 g, 10.0 mmol) and 10% palladium on carbon (168 mg) in tetrahydrofuran (10 mL) was stirred under hydrogen atmosphere at room temperature for 6 hr. Catalyst was removed by filtration and the filtrate was concentrated in vacuo to give the title compound (1.31 g, 9.49 mmol, 95%) as a pale brown solid.
