実験手順

To a cloudy orange mixture of 4-(1-ethyl-4-{2-[4-(1-pyrrolidinylmethyl)phenyl]-1H-pyrrolo[2,3-b]pyridin-4-yl}-1H-pyrazol-3-yl)aniline (280 mg, 0.61 mmol) in dry CH2Cl2 (6 mL) was added TEA (253 uL, 1.82 mmol), DMAP (4 mg, 0.03 mmol) and 2-methylpropanoyl chloride (77 uL, 0.73 mmol). The reaction was stirred for 15 min at room temperature, quenched with water and diluted with CH2Cl2 and brine. The aqueous layer was extracted with CH2Cl2 followed by 1% MeOH in CH2Cl2 and the combined extracts were dried (Na2SO4), filtered and concentrated under reduced pressure. The residue was purified by Gilson reverse phase HPLC (MeCN/H2O with 0.1% TFA). The clean fractions were neutralized with aqueous NaHCO3, extracted with three portions of CH2Cl2 followed by 1% MeOH in CH2Cl2, dried (Na2SO4), filtered and concentrated under reduced pressure to give 139 mg (43%) of the title product as a yellow solid. ESMS [M+H]+: 533.4.
