Participants

Reaction Steps

Oxalyl chloride (0.51 mmol, 45 μL) and DMF (catalytic amount) were added to 5-bromo-furan-2-carboxylic acid (0.18 mmol, 36 mg) in dichloromethane (3 mL). The reaction mixture was stirred for 40 minutes at room temperature. The organic solvents were removed in vacuo. The concentrate was re-dissolved in dichloromethane and 1-(2-fluoro-4-methanesulfonyl-phenyl)-4-(piperidin-4-ylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidine hydrochloride (0.16 mmol, 70 mg) and triethylamine (0.47 mmol, 66 μL) were added and stirred for 1.5 hours at room temperature. The progress of the reaction was monitored by thin layer chromatography and LCMS. Purification by HPLC provided Compound A115 as a white solid (45 mg, 41%). 1H NMR (400 MHz, CDCl3) δ (ppm): 8.74 (s, 1H); 8.25 (s, 1H); 7.87 (m, 3H); 7.00 (d, 1H); 6.49 (s, 1H); 4.50 (h, 1H); 4.34 (m, 2H); 3.42 (s broad, 2H); 2.70 (s, 3H); 2.28 (m, 2H); 1.85 (m, 2H). Exact mass calculated for C22H19BrFN5O4S2 580.45, found 582.3 (MH+).
