Reaction Steps

A solution of [3-((4,5-dihydrothiazol-2-yl)carbamoyl)phenyl]boronic acid (19 mg, 0.08 mmol) in EtOH (3.3 ml) was added to a solution of 3-iodo-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (20 mg, 0.07 mmol) in DME (12 ml). Pd(PPh3)4 (16 mg, 0.014 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) to yield BA30 (17.8 mg, 67% yield).
