Abstract

Improved process for preparing anthranylaldehyde derivatives of formula: <IMAGE> (Z<1> and Z<2> each represents hydrogen atom, a halogen atom, methyl group or trifluoromethyl group) is provided. The process comprises steps of (1) protecting aldehyde group of a o- halogenobenzaldehyde with a specific alkylamine derivative, then (2) reacting the thus protected compound with a corresponding aniline derivative, and finally, (3) treating the thus obtained product with an acid. The anthranylaldehyde derivatives, are useful as intermediates for preparation of anti-inflammatory and analgesic agents.
