Abstract: 

An efficient synthesis of N -phenylcarboxamodo-2-aryl-1, 2-dihydro- (4 H)-3, 1-benzoxazin-4-ones is described by cyclization reaction of some 2-(benzylidene-amino) -benzoic acids with phenyl isocyanate under reflux conditions in CHCl3. Higher yields of the products were produced in high purity with simple work-up.
