実験手順
To a solution of 5-{2-[(6-chloroquinolin-4-yl)methyl]-7-cyclopropylmethyl-4,6-dioxo-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-d]pyrimidin-3-yl}-1-methyl-1H-pyrrole-3-carbonitrile (0.42 g) in pyridine (5 mL) were added 4-chlorophenyl phosphorodichloridate (0.5 mL) and 3-nitro-1,2,4 triazole (0.15 g). After heating (Tb=50° C.) for 3 h, the reaction was diluted with ethyl acetate. The organic solution was washed with saturated NaHCO3 and brine, dried (Na2SO4), filtered and concentrated. The residue was dissolved in THF (10 mL) and ethanolamine (1.0 mL). After 3 h, the reaction was concentrated. This residue was purified by flash chromatography using a FlashMaster™ yielding 0.22 g, ES (M+H)+=529.
