Patent Claims:	1. R-(-)-(E)-[ 4-(2,4-Dichlorophenyl)-1,3-dithilan-2-ylidene]-1-imidazolylacetonitrile or a pharmaceutically acceptable salt thereof. 2. A pharmaceutical composition comprising as an active ingredient R-(-)-(E)-[4-(2,4-dichlorophenyl)-1,3-dithiolan-2-ylidene]-1-imidazolylace tonitrile, or a pharmaceutically acceptable salt thereof; together with a pharmaceutically acceptable carrier or diluent. 3. A process for producing R-(-)-(E)-[4-(2,4-dichlorophenyl)-1,3-dithiolan-2-ylidene]-1-imidazolylace tonitrile represented by formula (B): ##STR16## which comprises reacting an optically active glycol derivative represented by formula (II) with a dithiolate salt represented by formula (III): ##STR17## wherein X.sub.1 and X.sub.2 are the same or different and each represents a methanesulfonyloxy group, a benzenesulfonyloxy group, a p-toluenesulfonyloxy group, or a halogen atom: ##STR18## wherein M represents an alkali metal atom. 4. A method for preventing or treating mycosis which comprises administrating to a human or animal in need of such prevention or treatment, a pharmaceutically effective amount of R-(-)-(E)-[4-(2,4-dichlorophenyl)-1,3-dithiolan-2-ylidene]-1-imidazolylace tonitrile, or a pharmaceutical acceptable salt thereof.
