The hot reaction mixture was filtered through a Whatmann paper filter. The filtrate was diluted in ethyl acetate and washed with water and Brine. The organic layer was dried over anhydrous sodium sulfate then filtered and evaporated under reduced pressure. The residue was purified by silica gel chromatography (eluting gradient 0-20% pentane/ethyl acetate). The residue was triturated in n-Heptane, then filtered and dried to afford the expected compound (11 .73 g, 44% yield) as a beige solid. LCMS (MA) RT = 2.53 min, m/z = 238.2 (M+H)+. |
