Abstract
A process for preparing compounds of formula (I) wherein; R1 is hydrogen, C1-C4 alkoxy, arylalkoxy, halo or amino R2 is hydrogen, C1-C4 alkoxy, arylalkoxy, halo or amino R3 is a thermally-labile or acid-labile C4-C10 alkyl, C4-C10 alkenyl, or aryl(C1-C10 alkyl) group all having a tertiary carbon atom adjacent to the sulphur atom The process involves: 1) reacting a benzyl sulfide with a strong base to form a benzylic anion 2) condensing the benzylic anion with a benzaldehyde 3) reacting the condensation product with an acid chloride to produce an ester 4) treating the ester with a strong base to produce styryl sulfide 5) oxidizing the styryl sulfide with an oxidizing agent
