This compound was prepared by the condensation procedure 1A. The required intermediate 2-bromoethylphenyl sulphide may be prepared by condensing 1,2-bromoethane and thiophenol in sodium hydroxide solution, in a manner analogous to that used for preparation of the intermediates for compounds of Example Nos. 62-73, but a method which gives better yields uses the scheme: ##STR3## Condensation with ethyl 4-hydroxybenzoate gave 1-(4-ethoxycarbonylphenoxy)-2-phenylthio ethane, m.p. 50°-51°C.
