Reaktionsschritte
104 parts of 2-nitro-4-acetamidoanisole, 200 parts of methanol, 1.2 parts of a 30% aqueous solution of ammonia and 2 parts of a 50% suspension of palladium on charcoal, moist with water, in 2 parts of water are charged to an autoclave equipped with an aerating stirrer. The autoclave is pressurised with hydrogen and, at a pressure of 5 bar and a temperature of 100° C., hydrogenation is carried out for 2 hours. 2-Methoxy-5-acetamidoaniline is obtained in quantitative yield in a purity of >97% (analysis by liquid chromatography).
