Reaction Steps

A two liter autoclave was charged with 65.0 g of N,N-bis(2-methoxyethyl)-2,4-dinitrobenzamide, 1000 ml of methanol and 2.7 g of a 5% palladium on carbon/50% water catalyst. The mixture was hydrogenated at 800 psi hydrogen pressure while maintaining the temperature between 60°-100° C. Hydrogen uptake ceased after 30 min. The mixture was cooled, filtered, and the methanol removed at reduced pressure to give 53.2 g of N,N-bis(2-methoxyethyl)-2,4-diaminobenzamide, a red-brown viscous liquid.
