摘要

The present invention relates to a process for preparing 1-[6-(morpholin-4-yl)pyrimidin-4-yl]-4-(1H-1,2,3-triazol-1-yl)-1H-pyrazol-5-ol (I—enol form) or 2-[6-(morpholin-4-yl)pyrimidin-4-yl]-4-(1H-1,2,3-triazol-1-yl)-1,2-dihydro-3H-pyrazol-3-one (I—keto form) and sodium 1-[6-(morpholin-4-yl)pyrimidin-4-yl]-4-(1H-1,2,3-triazol-1-yl)-1H-pyrazol-5-olate (II) from 1,2,3-triazole (III), methyl bromoacetate (IV-Me-Br) or ethyl bromoacetate (IV-Et-Br), 4,6-dichloropyrimidine (VIII), morpholine (IX) and hydrazine (XII).
