反应详情

Into a 100-mL round-bottom flask, was placed a solution of trimethylsilanecarbonitrile (376 mg, 3.79 mmol) in acetonitrile (20 mL). Tetrabutylammonium fluoride (3.8 mL, 1 M in THF) was added to the reaction. This was followed by the addition of 5-(2-(hydroxymethyl)-4-methyl-1H-imidazol-5-yl)-2,4-dimethylbenzoic acid (compound 222.5, 190 mg, 0.73 mmol), in portions. The reaction mixture was stirred for 1 h at room temperature, then concentrated under reduced pressure. The residue was purified by silica gel chromatography with ethyl acetate/petroleum ether (1:1) as eluent to furnish 190 mg (97%) of the title compound as a yellow solid.
