To a solution of ethyl-3-bromooxopentanoate (O. G. Kulinkovich e.t al., Synthesis, 1986, 378–379) (1.26 g) in absolute ethanol (6 ml) was added 4-(trifluoromethyl)thiobenzamide (1.24 g). The reaction was heated to reflux and stirred at this temperature for 18 hours under nitrogen. The mixture was then allowed to cool to room temperature, prior to cooling in ice. This resulted in crystallization of the product which was filtered and washed with ice cold ethanol to afford the title compound as beige crystals.
