Reaction Steps

To an ice-cooled solution of 2-(2-chloro-6-fluorophenyl)-7-fluorothiazolo[5,4-c]pyridine (4.0 g, 14.16 mmol) in DCM (50 mL) was added m-CPBA (4.82 g, 0.028 mol) and the mixture was stirred at 5° C. for 1 hour. Additional m-CPBA (4.82 g, 28.0 mmol) was added and stirring at room temperature was continued for 18 hours. The suspension was diluted with DCM (50 mL) and washed with a potassium carbonate solution (100 mL). The aqueous phase was extracted with DCM (2×50 mL) and the combined organic layers were washed with water (100 mL), then dried (Na2SO4) and concentrated under reduced pressure. The resultant residue was triturated with diethyl ether (25 mL) to afford the title compound as a white solid (3.1 g, 73%). LCMS (Method E): RT=2.70 min, m/z: 299 [M+H+].
