To a solutionof 2-bromo-4-methyl-5-nitropyridine (5.00 g, 23.0 mmol) in tetrahydrofuran (THF)(30 ml) was added Raney nickel (slurry in water). The reaction mixture washydrogenated (balloon) overnight at room temperature. The mixture was filteredthrough Celite, and concentrated under reduced pressure. The residue waspurified by silica gel column chromatography (0-50% EtOAc in hexanes) to afford27 as a yellow solid (4.02 g, 93%yield).1H NMR (300 MHz, CDCl3): delta ppm2.15 (d, J = 0.9 Hz, 3 H), 7.14 (s, 1 H), 7.78 (s, 1 H).
