Reaction Steps

To 2-(4-aminophenyl)-6-methylbenzothiazole (5 g, 20.8 mmol) in pyridine (60 mL) was added para-toluenesulphonyl chloride (5.953 g, 31.2 mmol, 1.5 eq.) in pyridine (40 mL). The reaction mixture was heated at reflux for 10 mins, then cooled and water (100 mL) added. The white precipitate formed was collected on a filter, washed with water and dried under vacuum to give N-[4-(6-methylbenzothiazol-2-yl)phenyl]-4-methylbenzenesulfonamide as a white solid. The yield was 8.091 g (99%).
