Reaction Steps

2-methyl-3-nitro aniline (10 g, 0.005 mol) was taken in acetic acid (100 ml, 10 times) and cooled to 20° C. A solution of sodium nitrite (10 g, 0.14 mol, 2.25 eq) in water (25 ml) was added drop wise for 15 min at 20° C. The overall reaction mixture was stirred for 30 min at 20° C. and later stirred for 2 hrs at rt. Progress of the reaction was monitored by TLC (15% ethyl acetate/hexane, Rf˜0.2). On completion of the reaction, acetic acid was distilled off completely and the residue obtained was taken in cold water (200 ml). Solid thrown out was filtered and dried to yield the required product as an yellow colored solid (8.5 g, 68% yield).
