P-Chloroacetophenone → HCID 86751827, compound

Participants

Reaction Steps

Following a procedure similar to that described in Example 40(f), 0.18 ml of 4'-chloroacetophenone was reacted with 400 mg of 5-[4-(2-aminooxyethoxy)benzyl]thiazolidine-2,4-dione hydrochloride [prepared as described in Example 40(e)]. The reaction mixture was then concentrated by evaporation under reduced pressure, and the resulting residue was extracted with ethyl acetate. The extract was washed with water and the solvent was removed by distillation under reduced pressure. The residue was mixed with a mixture of diethyl ether, diisopropyl ether and hexane, and the mixture was then stirred. The resulting precipitate was collected by filtration, to give 360 mg of the title compound, melting at 118°-119° C.
