Procedure

A solution of methyl 4-(4-(chloromethyl)-5-methyloxazol-2-yl)benzoate (6.0 g, 22.64 mmol, 1.00 equiv), cyclohexanethiol (3.9 g, 33.62 mmol, 1.50 equiv) and cesium carbonate (11.1 g, 34.05 mmol, 1.50 equiv) in N,N-dimethylformamide (60 mL) was stirred under nitrogen overnight at 50° C. The reaction was then quenched by the addition of 30 mL of water. The precipitate was collected by filtration and washed with 3×10 mL of hexane to give 4.5 g (58%) of methyl 4-(4-(cyclohexylthiomethyl)-5-methyloxazol-2-yl)benzoate as a white solid after drying under vacuum.
