Abstract

PURPOSE: To prepare the titled compound at increased rate of reaction, in shortened reaction time, in high yield, by chlorinating a p-nitrophenol compound in a halogenated aliphatic hydrocarbon solvent, optionally in the presence of a Lewis acid catalysts.
CONSTITUTION: The objective compound is prepared by (1) dissolving p-nitrophenol, 2-chloro-p-nitrophenol or their mixture in a halogenated aliphatic hydrocarbon solvent, (2) if necessary, adding a Lewis acid catalyst such as AlCl3, etc. to the solution, and (3) chlorinating with a chlorination agent at 10°CW the reflux temp. for 1W30hr, or 0.1W10hr in case of using a Lewis acid catalyst. The solvent is, e.g. methylene chloride, chloroform, dichloroethane, etc., and the chlorination agent is, e.g. chlorine gas, SOCl2, etc.
EFFECT: The objective compound can be prepared without using a number of complex reaction steps, and the immediate melt decomposition of the produced compound can be prevented.
