发明名称 AN IMPROVED PROCESS FOR THE PREPARATION OF 2-AMINO-5,8-DIMETHOXY[1,2,4]TRIAZOLO[1,5-C]PYRIMIDINE FROM 4-AMINO-2,5-DIMETHOXYPYRIMIDINE
摘要 <p>5-Substituted-8-alkoxy[1,2,4]triazolo[1,5-c]pyrimidin-2-amines are manufactured from 4-amino-2,5-dialkoxypyrimidines in an improved process in which the generation of gaseous by-products is controlled by the continuous addition of hydroxylamine as a free base.</p>
