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 (40 mg), 1-pyridin-2-ylmethanamine (157 μl) and diisopropylethylamine (330 μl) were dissolved in 1,2-dichloroethane (5 ml), chloro-N,N,N′,N′-tetramethylformamidinium hexafluorophosphate (200 mg) was added, and the mixture was stirred at room temperature for 2 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 silica gel column chromatography, and the fraction eluted with ethyl acetate-hexane (1:9-1:0) was concentrated under reduced pressure to give the object compound (19 mg).
