실험 절차

A two liter autoclave was charged with 130.6 g of N-(2,4-dinitrobenzoyl)morpholine, 1200 ml methanol and 6.2 g of a 5% palladium on carbon/50% water catalyst. The mixture was hydrogenated at 800 psi while maintaining the temperature between 60°-100° C. Hydrogen uptake ceased after 30 min. The mixture was cooled, filtered and methanol removed at reduced pressure. The residue was crystallized from toluene to yield 97.1 g of N-(2,4-diaminobenzoyl)morpholine, mp 114°-115° C.
