Procedure
By a procedure similar to that described for the synthesis of 3,4-dihydro-2H-1,4-benzoxazine (Example 142), O-aminophenol and 2-chlorophenylacetyl chloride produces 3,4-dihydro-2-phenyl-2H-1,4-benzoxazine, m.p. 113°-116° which, according to the reaction scheme of Example 110 is converted to the title compound, m.p. 311°-313° .
