Procedure

A solution of oxalic acid in ether was added dropwise to a stirred solution of 2.0 g. of 1-(3-octylthiooctyl) imidazole in 30 ml. of anhydrous ether until precipitation was complete. The product was filtered off, washed with ether, air dried, and recrystallized from ethyl acetate to yield 1-(3-octylthiooctyl)imidazole oxalate, m.p. 105°-108° C.
