Participants

Reaction Steps

To a mixture of 52.24 g (0.150 mol, E/Z=3.5/96.5) of α-methoxyimino-2-(4-chloro-2-methylphenoxymethyl)phenylacetic acid produced in accordance with Example 5-(2), 0.57 g (0.0078 mol) of dimethylformamide and 203 g of toluene was added dropwise 25.9 g (0.204 mol) of oxalyl chloride over 3 hours while keeping at 60°-65° C., and the reaction was subsequently allowed to proceed at the same temperature for 1 hours and then 80° C. for 2 hours, which afforded 265 g of a toluene solution of α-methoxyimino-2-(4-chloro-2-methylphenoxymethyl)phenylacetyl chloride.
