Reaction Steps

A solution of N-Boc-3-formyl-5-indoleboronic acid pinacol ester (40 mg, 0.11 mmol) in EtOH (3.3 ml) was added to a solution of 3-iodo-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (30 mg, 0.10 mmol) in DME (12 ml). Pd(PPh3)4 (30 mg, 0.03 mmol) and saturated Na2CO3 (1.9 ml) were added and the reaction was heated to 80° C. under an argon atmosphere overnight. After cooling, the reaction was extracted with saturated NaCl and CH2Cl2. Organic phases were combined, concentrated in vacuo and purified by RP-HPLC (MeCN:H2O:0.1% TFA). The TFA from purification hydrolyzed the Boc to yield BA43. ESI-MS (M+H)+ m/z calcd 321.1, found 321.0.
