Diisopropylethylamine → [5-(4-Fluoro-phenyl)-2-(3-methoxy-2-triisopropylsilanyloxy-phenyl)-[1,3,4]thiadiazol-3-yl]-(2,4,6-trifluoro-phenyl)-methanone

Participants

Reaction Steps

To the solution of 5-(4-fluoro-phenyl)-2-(3-methoxy-2-triisopropylsilanyloxy-phenyl)-2,3-dihydro-[1,3,4]thiadiazole is added DIEA (3.09 mmol) and 2,4,6-tri-fluorobenzoyl chloride (3.09 mmol) and the reaction mixture is stirred for 12 hours at room temperature. After concentration, the residue is purified by automated column chromatography (hexane/EtOAc) to yield [5-(4-fluoro-phenyl)-2-(3-methoxy-2-triisopropylsilanyloxy-phenyl)-[1,3,4]thiadiazol-3-yl]-(2,4,6-trifluoro-phenyl)-methanone.
