Sulconazole (trade name Exelderm) is an antifungal medication of the imidazole class. It is available as a cream or solution to treat skin infections such as athlete’s footringwormjock itch, and sun fungus.[1][2] Although not used commercially for insect control, sulconazole nitrate exhibits a strong anti-feeding effect on the keratin-digesting Australian carpet beetle larvae Anthrenocerus australis.[3]

EXAMPLE 5Alternative Route to 1-[β-(R-carbonylthio)phenethyl]imidazolesA. Preparation of 1-[2,4-dichloro-β-(methylcarbonylthio)-phenethyl]imidazole, oxalate.

1-(β,2,4-Trichlorophenethylimidazole (1.19g) in 5 ml of dry tetrahydrofuran was added to preformed sodium thioacetate, generated in situ from 720 mg thioacetic acid and sodium hydride (480 mg 57% dispersion in mineral oil) in 20 ml. tetrahydrofuran and the mixture stirred and refluxed under nitrogen for 18 hours. The solvent was removed under reduced pressure, water (20 ml) added and the product extracted with ether. The extracts were washed with water, dried (MgSO4), evaporated and the residue chromatographed on silica gel eluting with 10-20% acetone in dichloromethane. The pure product in ether was treated dropwise with ethereal oxalic acid until precipitation was complete, and the thus obtained oxalate salt of 1-[2,4-dichloro-β-(methylcarbonylthio)phenethyl]imidazole recrystallized from acetone/ethyl acetate with mp
By substituting other available sodium thioacids for sodium thioacetate, other compounds of this invention may be prepared.

EXAMPLE 9A. Preparation of 1-[2,4-dichloro-β-(4-chlorobenzylthio)-phenethyl]imidazole

To a stirred solution of 330 mg sodium hydroxide in 30 ml methanol under nitrogen is added 810 mg of 1-[2,4-dichloro-β-(methylcarbonylthio)phenethyl]imidazole oxalate and the mixture is stirred at room temperature for ca. 30 minutes (until thin layer chromatography shows the disappearance of the ester). α,p-dichlorotoluene (350 mg) is then added, the solution stirred a further 15 minutes and the solvent removed under reduced pressure. Ether and water are then added to the residue and the ether extract washed with water, dried (MgSO4) and concentrated. Dropwise addition of nitric acid (d = 1.42) until precipitation is complete gives the nitrate salt of 1-[2,4-dichloro-β-(4-chlorobenzylthio)phenethyl]imidazole, recrystallized from acetone, mp 130.5°-132° C.
B. By using other compounds of this invention exemplified by those set forth in Examples 2 and 4 and other suitable (substituted) hydrocarbyl halides (or mesylates, tosylates), other compounds may be prepared.
