Participants

Reaction Steps

To a mixture of 4-(3-{[3-(t-butoxycarbonylaminomethyl)-4-cyanophenylamino]-[2-fluoro-5-methoxy-3-(2-triisopropylsilanyloxyethoxy)phenyl]methyl}-5-oxo-4,5-dihydro-[1,2,4]triazol-1-yl)oxazole-5-carboxylic acid methyl ester (41.1 mg) and THF (2 mL) there was added a 1M THF solution of tetrabutylammonium fluoride (0.100 mL). The mixture was stirred for 3 hours, and then ethyl acetate (30 mL) and water (15 mL) were added. The mixture was sufficiently shaken, and then the organic layer was separated off, washed with water (15 mL) and saturated aqueous sodium chloride (15 mL) in that order, and dried over anhydrous magnesium sulfate. The mixture was filtered to obtain a filtrate and the solvent in the filtrate was distilled off under reduced pressure to obtain the target compound (39.1 mg) as a colorless oil.
