Reaction Steps

[5-(4-Fluoro-phenyl)-2-(2-triisopropylsilanyloxy-phenyl)-[1,3,4]thiadiazol-3-yl]-(2,4,6-trifluoro-phenyl)-methanone (41 μmol), prepared in a similar manner as described for [5-(4-fluoro-phenyl)-2-(3-methoxy-2-triisopropylsilanyloxy-phenyl)-[1,3,4]thiadiazol-3-yl]-(2,4,6-trifluoro-phenyl)-methanone in example 3, is treated with tetrabutylammonium fluoride (1.0 M in THF) (48 μmol) at room temperature for 40 minutes. The solvent is removed in vacuo and dried over MgSO4 to yield [5-(4-fluoro-phenyl)-2-(2-hydroxy-phenyl)-[1,3,4]thiadiazol-3-yl]-(2,4,6-trifluoro-phenyl)-methanone to be used without further purification.
