Thiophosgene → 5-Bromo-6-isothiocyanatoquinoxaline

Participants

Reaction Steps

To a stirred solution of 6-amino-5-bromoquinoxaline hydrobromide (10 g) in distilled water (150 ml) is added thiophosgene (3 ml). The solution is stirred for two hours at room temperature and the resultant precipitate is collected by filtration, washed with water, and dried to afford 5-bromo-6 -isothiocyanato-quinoxaline.
