An ice cold solution of 1 gram of 2-(2-aminophenyl)oxazolo[5,4-b]pyridine in 15 ml. of dry pyridine was treated with 1 gram of benzoyl chloride slowly. The reaction mixture was diluted with ice-water and stirred for 10 minutes and the resulting solid was collected on a filter and recrystallized from benzene to give 2-(2-benzoylaminophenyl)oxazolo[5,4-b]pyridine, m.p. 197°-198° C.
