Participants

Reaction Steps

A stirred solution of 4-ethyl-5-methyl-2-nitro-aniline [484 mg, Reference Example 31(b)] in methanol (20 ml) was treated with tin chloride (5.09 g), then heated at reflux for 16 hours and then cooled to ambient temperature. The pH of the reaction mixture was adjusted to pH 8 by addition of aqueous sodium bicarbonate and then this mixture was extracted with ethyl acetate. The organic extracts were dried over magnesium sulfate and then evaporated to give 4-ethyl-5-methyl-phenylene diamine (374 mg) as an off-white solid. LC-MS (METHOD B): RT=1.80 minutes; 151.25 (M+H)+. (b) 4-Isopropyl-5-methyl-phenylene diamine
