실험 절차

A mixture of 2-amino-4-methoxybenzenethiol (7.0 g, 0.045 mole), sodium hydroxide (4.4 g, 0.11 mole) and carbon disulfide (8.06 g, 0.11 mole) in 90% aqueous ethanol (100 ml.) was heated at reflux for 2 hours, filtered, diluted with ice-water and acidified with hydrochloric acid to give 7.0 g of 5-methoxy-2-benzothiazolethiol which melts at 192°-4° C. after recrystallization from benzene.
