To a solution of 2-[3-({[5-(5-chloro-2-fluorophenyl)-1,2,4-oxadiazol-3-yl]methyl}thio)-5-(2-thienyl)-4H-1,2,4-triazol-4-yl]ethanol in a mixture of DMF (1 ml) and pyridine (0.5 ml) was added methanesulfonyl chloride (20 uL). The mixture was stirred at r.t. for 24 h before poured onto water (10 ml). The crude product was filtered off and purified by chromatography on silica gel using 0-5% MeOH in DCM as eluent to give 43 mg of the title compound, which was used directly in the next step.
