Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrochloric Acid | HCID 313 | — |
| Reactant | 2-Methylpiperazine | HCID 66057 | — |
| Reactant | 2-Bromothiazole | HCID 76430 | — |
| Product | HCID 62480333 | HCID 62480333 | 90.2% |
Reaction Steps
30.06 g (300.0 mmol) of 2-methylpiperazine were combined with 4.51 ml (50.0 mmol) of 2-bromothiazole. This mixture was fused and refluxed 5 min. The reaction mixture was cooled and taken up in 10% strength hydrochloric acid and washed with EA. The aqueous phase was set to pH>12 with a 10% strength aq. NaOH solution and then extracted with EA. The organic phase was dried over MgSO4 and conc. in vacuo. There were obtained 8.26 g (45.1 mmol, 90%) of 3-methyl-1-thiazol-2-ylpiperazine.
