Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | p-Toluenesulfonic acid | HCID 6101 | — |
| Reactant | Caprolactam | HCID 7768 | — |
| Reactant | 2-Aminothiophenol | HCID 8713 | — |
| Product | 2-Benzothiazolepentanamine | HCID 12262422 | — |
Reaction Steps
A mixture of caprolactam (62 g; 0.55 mole) and o-aminothiophenol (68.8; 0.55 mole) was heated with p-toluenesulfonic acid (4.3 g) at 190°-260° for 41/2 hrs. while removing water by distillation. The product was essentially pure 2-(5-aminopentyl)benzothiazole.
