실험 절차

A solution of 6-[[2-(tert-Butyl-dimethyl-silanyl)-3-methyl-3H-imidazol-4-yl]-(4-chloro-phenyl)-hydroxy-methyl]-1-cyclopropylmethyl-4-(3-trimethylsilanylethynyl-phenyl)-1H-quinolin-2-one (4.50 g crude) in THF (100 mL) was treated with tetrabutylammonium chloride (1 M in THF, 10.0 mmol). The reaction mixture was stirred at room temperature for 12 hours, poured into H2O (200 mL), and extracted with ethyl acetate (3×100 mL). The combined organic extracts were washed with 1N HCl (100 mL), aqueous NaHCO3 (100 mL), and brine (100 mL), dried (MgSO4), filtered, and concentrated in vacuo to give a light green foam. Purification by flash column chromatography (silica, EtOAc:pet. ether:NH4OH 1:1:0.01) gave 6-[(4-Chloro-phenyl)-hydroxy-(3-methyl-3H-imidazol-4-yl)-methyl]-1-cyclopropylmethyl-4-(3-ethynyl-phenyl)-1H-quinolin-2-one (1.82 g, 51%) as a yellow powder.
