実験手順

Sodium hydride (60% in mineral oil, 27 mg, 0.55 mmol) was added to a solution of 3′-(2-methoxycarbonylamino-3-methyl-butyryl)-4-[4-(4-{2-[1-(2-methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-1H-imidazol-4-yl}-phenylethynyl)-phenyl]-2′,3′,4′,5′-tetrahydro-1H-[2,4′]biimidazolyl-1′-carboxylic acid tert-butyl ester (248 mg, 0.23 mmol) in dimethylformamide (8 mL) under an atmosphere of nitrogen at 0° C. After 15 minutes 2-(trimethylsilyl)ethoxymethyl chloride (107.5 μL, 0.48 mmol) was added and the reaction was allowed to warm to ambient temperature. After 2 hours the solvent was removed under reduced pressure. The residue was taken up in dichloromethane (50 mL) washed with water (20 mL), and dried over sodium sulfate and filtered. The solvent was removed under reduced pressure. The residue was subjected to flash chromatography with eluent of (10% methanol in ethyl acetate) and hexane. The product-containing fractions were combined and the solvent was removed under reduced pressure to yield 3′-(2-methoxycarbonylamino-3-methyl-butyryl)-4-[4-(4-{2-[1-(2-methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazol-4-yl}-phenylethynyl)-phenyl]-1-(2-trimethylsilanyl-ethoxymethyl)-2′,3′,4′,5′-tetrahydro-1H-[2,4′]biimidazolyl-1′-carboxylic acid tert-butyl ester (410 mg, 0.36 mmol). C58H85N9O10Si2 calculated 1123.6 observed [M+1]+ 1124.7; rt=3.10 min.
