Reaction Conditions:
with hydrogen in ethyl acetate at 20; for 2 h;
Steps:
25.1
step 1 : To a solution of 2-chloro-5-nitropyridin-4-amine (4.50 g, 25.93 mmol) in EtOAc (100 mL) was added Raney nickel (0.45 g) followed by stirring under hydrogen at RT for 2 h. The reaction mixture was filtered and the filtrate concentrated under reduced pressure to afford 4.00 g (ca. 100%) of crude 6- chloropyridine-3,4-diamine as yellow oil. MS (ESI): m/z = 144.3 [M+l]+.
