반응 단계

Title compound 11A, 1-(4-amino-phenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-ylamine (37 mg, 1.1 eq, 0.16 mmol) was added to a solution of 3-methoxypropionic acid (15.5 mg, 1.0 eq, 0.15 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (25 mg, 1.0 eq, 0.16 mmol), 1-hydroxybenzotriazole (20 mg, 1.0 eq, 0.15 mmol) in DMF (1 ml) which had been stirred for 10 minutes under an inert atmosphere. The reaction was stirred at room temperature for 18 hours, after which methanol (1 ml) was added, and solvent was removed in vacuo. The resultant solid was washed with water and purified by semi-preparative HPLC to yield the title compound as a white solid (9.3 mg, 0.03 mmol, 20%). LCMS: [M+H]+=313, Rt=1.31 min, 100% purity.
