Synthesis of 2,6-difluoro-N-(3-[11C]methoxy-1H-pyrazolo[3,4-b]pyridine-5-yl)-3-(propylsulfonamidio)benzamide as a new potential PET agent for imaging of B-Raf(V600E) in cancers.
Bioorg. Med. Chem. Lett. 23(4) , 1017-21, (2013) 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 t... |

Molecular structure and vibrational spectra of 3-amino-5-hydroxypyrazole by density functional method.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 71(5) , 1776-82, (2009) In this work, we report a combined experimental and theoretical study on molecular and vibrational structure of 3-amino-5-hydroxypyrazole (3A5HP). The Fourier transform infrared and Fourier transform Raman spectra of 3A5HP were recorded in the solid phase. Th... |
