| Reactant | 4-Methoxy-2-aminobenzothiazole | HCID 21622 | — |
| Solvent | Ethanethiol | HCID 6343 | — |
| Product | 2-Amino-4-hydroxybenzothiazole | HCID 24057 | — |
Reaction Steps
A solution of AICl3 (5 mmole) in EtSH (10 mL) was cooled to 0° C. and treated with 2-amino-4-methoxybenzothiazole (1 mmole). The mixture was stirred at 0-5° C. for 2 h. Evaporation and extraction gave 2-amino-4-hydroxybenzothiazole as white solid.
