53% | With n-butyllithium; In tetrahydrofuran; hexane; at -78℃; for 0.333333h; | To a solution of 1 ,3-dichloro-2-fluoro-5-iodo-benzene (CAS 133307-08-1 , 50 g) and 2,2,2-trifluoro-/S/-methoxy-/S/-methyl-acetamide (40.5 g) in THF (800 ml.) at -78C was added n-BuLi (82.5 ml_, 2.5 M in hexanes). The reaction was stirred for 20 min, then quenched by saturated aqueous NH4CI solution and extracted with ethyl acetate. The organic layer was dried (Na2S04), filtered, and concentrated. The residue was purified by flash chromatography on silica gel to afford the product (24 g, 53%). H NMR (400 MHz, CDC ): delta 8.0 (m, 2H). |
