Versuchsvorschrift

5-Butyl-pyridine-2-carboxylic acid (92 mg, 0.51 mmol) and isopropyl chloroformate (70 μL, 0.51 mmol) were dissolved in DMF and stirred at room temperature for 40 min. 1-(4-Methanesulfonyl-phenyl)-4-(piperidin-4-yloxy)-1H-pyrazolo[3,4-d]pyrimidine hydrochloride (70 mg, 0.17 mmol) and triethylamine (72 μL, 0.51 mmol) were added next and continued to stir for 24 hours. Progress of the reaction was monitored by TLC and LCMS. Removal of organic solvents in vacuo and purification by HPLC afforded Compound A125 as a white solid (13 mg, 13%). Exact mass calculated for C27H30N6O4S 534.63, found 535.20 (MH+).
