5-(2-Methyl-2-nitropropoxy)salicylamide → 5-(2-Amino-2-methylpropoxy)salicylamide

Participants

Reaction Steps

11.5 g 5-(2-methyl-2-nitropropoxy)salicylamide are hydrogenated in 150 ml of methanol at 40°-50° and 80 bar over 5 g of Raney nickel until hydrogen absorption ceases. By filtration and concentration of the filtrate by evaporation, crude 5-(2-amino-2-methylpropoxy)salicylamide is obtained, which, after standing for a relatively long period, crystallises from isopropanol and melts at 115°-117°.
