実験手順
The compounds of this invention can be prepared by various synthetic routes. Benary and Bitter, Ber. 61, 1058 (1928) taught the synthesis of an intermediate disodium salt of 1,5-dihydroxy-2,4-diphenyl-1,4-pentadien-3-one by the condensation of 1,3-diphenyl-2-propanone with ethyl formate in the presence of sodium methoxide. The intermediate pentadienone is neutralized by strong acid and forms 3,5-diphenyl-4-pyrone. Reaction of the pyrone with ammonium acetate at an elevated temperature produces 3,5-diphenyl-4(1H)-pyridone.
