Reaction Steps

Title compound 11B, 1-(3-amino-phenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-ylamine (40 mg, 1.1 eq, 0.18 mmol) was added to a solution 3-methylpentanoic acid (20 μl, 1.0 eq, 0.16 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (27 mg, 1.1 eq, 0.18 mmol), 1-hydroxybenzotriazole (22 mg, 1.0 eq, 0.17 mmol) in DMF (1 ml) which had been stirred for 10 minutes under an inert atmosphere. The reaction was stirred at room temperature for 48 hours, after which methanol (1 ml) was added, and the solvents were removed in vacuo. The residue was purified by mass direct preparative HPLC to yield the title compound as a white solid (28 mg, 0.09 mmol, 54%). LCMS: [M+H]+=325, Rt=1.67 min, 100% purity.
