A method for the preparation of 3-chloromethyl derivatives of 4-alkylnitrobenzenes from the corresponding amidomethyl derivatives with phosphorus oxychloride or with phosphorous oxychloride and inert solvents. This process also relates to 3-chloromethyl-4-alkylnitrobenzenes which are useful intermediates for the preparation of certain substituted 2,6-dinitroaniline pre-emergence herbicides.
