| Reactant | Hydrochloric Acid | HCID 313 | — |
| Reactant | 1-Methylpiperazine | HCID 53167 | — |
| Reactant | 4-chloro-3-[(methylamino)sulfonyl]benzoic acid | HCID 851354 | — |
| Product | HCID 70638561 | HCID 70638561 | — |
Reaction Steps
250 Grams of 4-chloro-3-methylsulfamoylbenzoic acid (1.0 mole) were stirred with 0.3 l of N-methylpiperazine for 4 hours at 130° C. When the hot reaction solution was introduced into 2 l of 2N HCl, the final product precipitated immediately in a crystalline form. The crude product was purified by recrystallization from a 2:2:1 mixture of ethanol/water/dimethylformamide.
