Procedure

Into a 50-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed [5-bromo-3-(trifluoromethyl)-1,2-thiazol-4-yl]methanol (100 mg, 0.38 mmol, 1.00 equiv), dioxane (3 mL), (2,4-dimethylphenyl)boronic acid (113 mg, 0.75 mmol, 1.97 equiv), Pd(PPh3)4 (44 mg, 0.04 mmol, 0.10 equiv), K3PO4 (402 mg, 1.89 mmol, 4.96 equiv). The resulting solution was stirred for 3 h at 90° C. in an oil bath. The solvent was removed and the residue was applied onto a TLC plate with ethyl acetate/petroleum ether (1:3). This resulted in 100 mg (crude) of [5-(2,4-dimethylphenyl)-3-(trifluoromethyl)-1,2-thiazol-4-yl]methanol as yellow oil.
