Reaction Steps
A mixture of 1.20 g (5 mmoles) of 2-(p-nitrophenyl)benzoxazole, 0.80 g (8.5 mmoles) of phenol, 2 g of potassium carbonate and 15 ml of NMP is stirred and refluxed under nitrogen atmosphere for one hour. The title product is recovered from the resulting solution as described in Example 1. The recovery is 1.15 g (80.4 percent yield). The product has a melting point of 70° C.-71° C. The experiment is repeated using 2-4(p-fluorophenyl)benzoxazole as the reagent and the title product is obtained in 90 percent yield.
