| titleOfInvention |
Process for preparing n-(2,6-dichloro-3-methylphenyl)-5-7-dihalo[1,2,4]triazolo[1,5a]pyrimidine-2-sulfonamide by cyclization and halo-dehydroxylation |
| abstract |
The invention relates to a process for making DCSA by cyclization of DCM-ATSA with an acid and phosphorus pentachloride to produce DHSA and two isomeric compounds known as HCSA. The resulting compounds from the cyclization are halo-dehydroxylated to produce DCSA. |
