Participants

Reaction Steps

A mixture of 19.5 parts of N-[4-(2,4-dioxo-3-propyl-1-imidazolidinyl)phenyl]acetamide and 480 parts of concentrate hydrochloric acid was stirred and refluxed for 5 hours. The reaction mixture was cooled, the precipitated product was filtered off and dissolved in a mixture of methanol and water. The solution was neutralized with a sodium hydrogen carbonate solution and the product was extracted with trichloromethane. The extract was dried, filtered and evaporated, yielding 15 parts (90%) of 1-(4-aminophenyl)-3-propyl-2,4-imidazolidinedione; mp. 133.2° C. (23).
