2-Methoxyethanol → HCID 23048844, compound

Participants

Reaction Steps

A mixture of 33.9 parts of 4-butyl-2-(4-nitrophenyl)-1,2,4-triazine-3,5(2H,4H)-dione, 2 parts of a solution of thiophene in methanol 4% and 400 parts of 2-methoxyethanol was hydrogenated at normal pressure and at room temperature with 3 parts of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated, yielding 29 parts (92.8%) of 2-(4-aminophenyl)-4-butyl-1,2,4-triazine-3,5(2H,4H)-dione as a residue (int. 28).
