To a mixture of 2-(3,4-dimethoxyphenyl)-5-nitropyridine (Interchim, Montlucon, France, 2.85 g, 10.95 mmol) in MeOH (27 ml) and THF (27 ml), Ra/Ni catalyst (1.10 g, 10.95 mmol) was added and shaked under hydrogen at rt for 15 h. After that, the RM was filtered over celite, the catalyst was washed with MeOH and the filtrate was evaporated to dryness to give the title compound as an off-white solid. (HPLC: tR 2.22 min (Method A); M+H=231 MS-ES)
