Procedure

The 2-(5-chloro-2-nitrophenoxy)benzaldehyde was prepared as follows: To 16.2 g of 2,4-dichloronitrobenzene stirred at 170° was added 7.1 g of the potassium salt of salicylaldehyde, monohydrate, in portions over 1.5 hours. The mixture was stirred at 170° C. for two hours, triturated with 150 ml of CH2Cl2 and filtered. The filtrate was evaporated to a red oil and the excess dichloronitrobenzene was removed by steam distillation to leave the product.
