Reaction Steps

A mixture containing one gram (3.2 mmoles) of 4,5-diphenyl-2-(p-fluorophenyl)-1,3-oxazole, 1.2 g (12 mmoles) of phenol, 2 g (14.5 mmoles) of anhydrous potassium carbonate and 10 ml of N-methylpyrrolidone (hereinafter NMP) is stirred and refluxed under nitrogen atmosphere for 40 minutes when gas chromatograph analysis indicates the disappearance of the starting material and the formation of a new compound. The reaction mixture is cooled, diluted with 30 ml of water, and stirred for 30 minutes. The colorless precipitate is filtered and recrystallized from 95 percent ethanol. The title compound (1.22 g, 99 percent yield) is recovered. The product has a melting point of 125° C.-126° C.
