ABSTRACT The present invention is relates to a one pot synthesis of 6-fiuoro-3-hydroxy-2-pyrazine carbonitrile and its pharmaceutical!)' acceptable salts, which is an intermediate in the preparation of Favipiravir.

The present invention relates to a crystalline form of 2-(3,5-dichlorophenyl)benzo[d]oxazole-6-carboxylic acid (Tafamidis) and an improved, industrially viable process for its preparation. The novel crystalline form is characterized by a distinctive powder X-ray diffraction (XRPD) pattern exhibiting characteristic pea...
