A new concise, facile, and efficient method for the synthesis of 3-hydroxy-5,6-diphenylpyrazolo[3,4-b]pyridine derivatives has been described. The cyclocondensation of isoflavones with 3-amino-5-hydroxypyrazole in the presence of sodium methoxide gave fused heteroaromatic 3-hydroxy-5,6-diphenylpyrazolo[3,4-b]pyridines in moderate to good yields.

The authentic standard 2,6-difluoro-N-(3-methoxy-1H-pyrazolo[3,4-b]pyridine-5-yl)-3-(propylsulfonamidio)benzamide was synthesized from 2,6-difluorobenzoic acid and 3-amino-5-hydroxypyrazole in 9 steps with 1% overall chemical yield. Direct desmethylation of the reference standard with TMSCl/NaI gave the precursor 2,6-difluoro-N-(3-hydroxy-1H-pyrazolo[3,4-b]pyridine-5-yl)-3-(propylsulfonamidio)benzamide for radiolabeling in 70% yield. The target tracer 2,6-difluoro-N-(3-[(11)C]methoxy-1H-pyrazolo[3,4-b]pyridine-5-yl)-3-(propylsulfonamidio)benzamide
