Procedure
A solution of 80 mg. of 5-amino-2-phenyloxazolo[5,4-b]pyridine in 1 ml. of pyridine was treated with 0.07 ml. of benzoyl chloride. After standing 1 hour the mixture was diluted with ice-water. The precipitate was collected and recrystallized from methanol to give 5-benzoylamino-2-phenyloxazolo[5,4-b]pyridine, m.p. 191°-192° C.
