Versuchsvorschrift

Title compound 11B, 1-(3-amino-phenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-ylamine (30 mg, 1.1 eq, 0.13 mmol) was added to a solution 1-methyl-1H-imidazole-2-carboxylic acid (15 mg, 1.0 eq, 0.12 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (20 mg, 1.1 eq, 0.13 mmol), 1-hydroxybenzotriazole (16 mg, 1.0 eq, 0.12 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 the solvents were removed in vacuo. The residue was then triturated with methanol and the resultant solid was isolated by filtration to yield the title compound as a yellow solid (3 mg, 0.01 mmol, 8%). LCMS: [M+H]+=335, Rt=1.48 min, 94% purity.
