Reaction Steps

To a solution of dichloroacetyl chloride (1.8 ml.) in methylene chloride (15 ml.) was added 2-hydroxyimino-(4-chlorophenyl)acetic acid (anti-isomer) (1.5 g.) and the suspension stirred for two hours at room temperature. During this time most of the material dissolved. The solid was removed, washed with petroleum (b.p. 40°-60°) and the washings and filtrate were combined, kept at 5° overnight and the resulting solid was collected and dried to give the title acid (2.0 g; 85%), m.p. 80°, λmax. (EtOH) 258 nm (ε 12,280), λmax. (Nujol) 1774 (ester), 1750 and 1722 cm.-1 (CO2H).
