Isopropyl chloroformate → {4-[1-(4-Methanesulfonyl-phenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yloxy]-piperidin-1-yl}-(5-morpholin-4-ylmethyl-furan-2-yl)-methanone

Participants

Reaction Steps

5-Morpholin-4-ylmethyl-furan-2-carboxylic acid (0.12 mmol, 25 mg), and isopropylchloroformate (0.12 mmol, 17 μL) and triethylamine (0.12 mmol, 17 μL) were dissolved in DMSO (2 mL) and stirred for 30 minutes at room temperature. Then, 1-(4-methanesulfonyl-phenyl)-4-(piperidin-4-yloxy)-1H-pyrazolo[3,4-d]pyrimidine (0.12 mmol, 50 mg) and excess triethylamine were added. The mixture was heated in a microwave for 5 minutes at 120° C. The progress of the reaction was monitored by thin layer chromatography and LCMS. Purification by HPLC provided compound A116 as a white solid. LCMS (ESI), m/z 567.3 (MH+, 100%).
