実験手順
2.5 gms of methyl 2,6-diphenyl-1-methyl-4-oxonicotinate was suspended in 28 mls of 5% aqueous sodium hydroxide 8 hours, cooled, and filtered to remove residual insolubles. The clear basic solution was then acidified with dilute HCl to provide a white precipitate of 2,6-diphenyl-1-methyl-4-oxonicotinic acid. Recrystallization from methylene chloride/ether provided 2.4 gms of product. mp=209°-211° (dec).
