63% | Reaction performed in parallel in 7 batches of 500 mg of 6 in a carrousel. From 3-bromo-5-chloropyrazolo[1,5-a]pyrimidine (6) (500 mg, 2.151 mmol), (5-amino-6-methoxypyridin-3-yl)boronic acid pinacol ester (538 mg, 2.151 mmol,), PdCl2(PPh3)2 (75 mg) in 1,2-DME (9 mL) and Na2CO3 (aq sat sol, 4.3 mL) heated at 80 C in semi-pressure tubes for 30 min. Then <strong>[199609-62-6]3-(N-Boc-aminomethyl)phenylboronic acid</strong> (675 mg, 2.689 mmol,) PdCl2(PPh3)2 (45 mg) were added and the mixture was heated at 100 C for 5 h. Purification of all batches together using gradient from 0% to 100% of EtOAc in cHex afforded 20 (4.23 g, 63%). LCMS (ESI): Rt = 4.68 min, m/z = 447.10 [M+ H]+. |
