Reaction Steps

To a solution of (5-bromo-1,3,4-thiadiazol-2-yl)methanol (1.2 g, 6.153 mmol) in toluene (40 mL) and ethanol (40 mL) was added 4-fluorophenyl boronic acid (1.026 g, 7.384 mmol) and 2 M solution of aqueous Na2CO3. The reaction mixture was degassed with argon, Pd(PPh3)4 (0.354 g, 0.355 mmol) was added, the reaction mixture again degassed with argon for 10 min, and the mixture heated to 100° C. for 2 h. The reaction mixture was evaporated under vacuum to remove the ethanol, diluted with water (50 mL), extracted with ethyl acetate (200 mL), dried over sodium sulfate, filtered and evaporated under reduced pressure to obtain crude product. The crude product was purified by Biotage IsoleraOne® column (using 30% ethyl acetate and hexane) to give (5-(4-fluorophenyl)-1,3,4-thiadiazol-2-yl)methanol as pale yellow solid (0.85 g, 65% yield); LC-MS m/z calculated for [M+H]+ 211.03, found 211.1.
