Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Propargyl bromide | HCID 7842 | — |
| Reactant | 2-Methylbenzothiazole | HCID 8446 | — |
| Product | 2-Methyl-3-(prop-2-yn-1-yl)-1,3-benzothiazol-3-ium bromide | HCID 182410 | 69.1% |
Reaction Steps
14.9 g of 2-methylbenzothiazole and 12.5 g of propargyl bromide were heated at 80 to 100° C on a hot water bath for 3 hours. The precipitated crystals were washed with acetone to obtain 18.5 g of 2-methyl-3-propargylbenzothiazolium bromide, m.p. 214°- 215° C.
