HCID 848877, compound → Phthalimide

Participants

Reaction Steps

11.8 Grams (0.05 mole) of N-(tert-butylthio)phthalimide and 8.5 grams (0.05 mole) of 2-mercaptobenzothiazole in 200 ml of benzene are stirred at 70° C for 6 hours. The reaction mixture is cooled and filtered to obtain 7.1 grams of phthalimide (white solid, m.p. 231° C). The benzene is stripped from the filtrate by evaporation to give a solid residue. The residue recrystallized from methanol gives 9.3 grams of 2-(tert-butyldithio)benzothiazole, m.p. 80.0°-80.5° C. Another 3.0 grams of product are obtained upon concentration of the alcoholic filtrate.
