Versuchsvorschrift

A stirred solution of benzothiazole-2-sulfonamide (2.14 g, 0.01 mole), palladium acetate (2.25 g, 0.01 mole), lithium acetate dihydrate (1.65, 0.025 mole) and potassium dichromate (5.9 g, 0.02 mole) in acetic acid (25 ml) is heated on a steam bath for 24 hours then poured into H2O (100 ml) to give 2-sulfamoyl-6-benzothiazolyl acetate which melts at 193°-4° C. after recrystallization from 2-propanol.
