A solution of 31.8 g (0.11 m) of 2,3-dichloro-4-hydroxy-2'-fluorobenzophenone of Example 2B and 15.29 g (0.22 m) of hydroxylamine hydrochloride in 150 ml of pyridine is refluxed 64 hours. The pyridine is evaporated in vacuo, 5% HCl added, extracted with ethyl acetate, dried (Na2SO4) and evaporated to give 32 g (96%) of 2,3-dichloro-4-hydroxy-2'-fluorobenzophenone oxime. An analytical sample is recrystallized from ethanol/H2O, m.p. 168°-175° C. TLC indicates the product is a mixture of isomers.
