Procedure

Methyl 2-chloro-4-fluorobenzoate (1.92 g, 10.2 mmol, 1 eq), cesium carbonate (3.74 g, 11.5 mmol, 0.13 eq) and benzyl mercaptan (1.3 g, 10.5 mmol, 1.03 eq) were combined in dimethyl sulphoxide (20 ml) and the reaction mixture heated at 50° C. for 4 hours. The reaction mixture was poured into ethyl acetate (10 ml) then washed with water (10 ml). The organic phase was dried over sodium sulphate, evaporated to yield the title compound as pink oil (2.82 g, 9.63 mmol, 95%).
