Participants

Reaction Steps

3-[(tert-Butoxycarbonyl)amino]-N-({2-tert-butyl-4-[(furan-2-ylmethyl)amino]pyrimidin-5-yl}carbonyl)-N-(2-methylpropyl)-L-alanine (27 mg), benzylamine (200 μl) and diisopropylethylamine (300 μl) were dissolved in 1,2-dichloroethane (5 ml), chloro-N,N,N′,N′-tetramethylformamidinium hexafluorophosphate (100 mg) was added, and the mixture was stirred at room temperature for 3.5 hr. The reaction mixture was diluted with saturated aqueous sodium hydrogen carbonate, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and the solvent was evaporated under reduced pressure. The residue was subjected to reversed-phase preparative HPLC, and fractions eluted with water-acetonitrile (9:1) to acetonitrile were collected. The mixture was basified (pH 10) with saturated aqueous potassium carbonate solution, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the object compound (19 mg).
