Participants

Reaction Steps

To a stirred and heated (100° C.) solution of 10 parts of 4-(1H-imidazol-1-ylmethyl)benzenamine in 50 parts of poly phosphoric acid were added 15 parts of ethyl 3-oxobutanoate. The whole was stirred for 4 hours at 140° C. 100 Parts of water were added to the mixture and the whole was neutralized with potassium carbonate. The product was extracted with a mixture of ethyl acetate and methanol. The extract was dried, filtered and concentrated. The concentrate was crystallized from a mixture of 2-propanone and methanol. The product was filtered off and dried, yielding 2 parts (14.4%) of 6-(1H-imidazol-1-ylmethyl)-2-methyl-4(1H)quinolinone; mp. 245.5° C. (decomp.) (compound 51).
