One-tenth mol of methyl-m-nitrosalicylate is dissolved in 250 ml. of ethyl acetate and 10 gms. of Raney nickel added. The mixture is placed in a suitable container to permit pressure hydrogenation and hydrogen gas is passed into the solution. When the gas pressure reaches 10 pounds psi. at 80° C., the mixture is agitated and when the absorption of hydrogen has reached equilibrium, it is shaken for four hours and cooled. The mixture is filtered and the formed methyl-m-aminosalicylat is isolated by distillation and is obtained as an oily compound which distills at 126° C. at 2 mm. Hg. pressure.
