PROCESS FOR THE PREPARATION OF SUBSTITUTED N-(ARYL)-1,2,4-TRIAZOLOPYRIMIDINE-2- SULFONAMIDES |
| 摘要 |
<p>The preparation of N-(aryl)-1,2,4-triazolo- pyrimidine-2-sulfonamides by the coupling of substituted 1,2,4-triazolopyrimidine-2-sulfonyl halides with aryl amines of substantially reduced nueleophilie reactivity is facilitated by conducting the reaction in the presence of a pyridine base and a catalytic amount of dimethyl sulfoxide.</p> |
