Participants

Reaction Steps

3.5 gms of 2,6-diphenyl-3-ethoxycarbonyl-4-pyrone was dissolved in 33 mls of methanol. 2 mls of glacial acetic acid was added. 13.3 mls of 40% aqueous methylamine was then added very slowly at room temperature. After 6 hours the reaction mixture was diluted with 200 mls of water and extracted with methylene chloride. Evaporation yielded 3.5 gms of ethyl 2,6-diphenyl-4-oxonicotinate which was recrystallized from methylene chloride/ether. mp=177°-179°
