Butoconazole (trade names Gynazole-1, Mycelex-3) is an imidazole antifungal used in gynecology. It is administered as a vaginal cream.^[1]^[2]

Synthesis

Butoconazole synthesis:^[3]^[4]

Reaction of epichlorohydrin with 4-Chlorobenzyl magnesium bromide leads to 1-chloro-4-(4-chlorophenyl)butan-2-ol (3). Displacement with sodium imidazole, conversion of the secondary alcohol to the chloride (SOCl2), and displacement with 2,6-dichlorobenzenethiol concludes the synthesis of the antifungal butoconazole.
