Participants

Reaction Steps

To a mixture of 15 ml of an aqueous solution of 20% potassium hydroxide and 50 ml of methanol was added 2.2 g of 2-(p-methoxycarbonylphenyl)imidazo[2,1-b]benzothiazole and the mixture was refluxed for 30 minutes. After the reaction was over, 4 ml of acetic acid was added to the reaction mixture and the crystals which had formed were recovered by filtration, washed successively with water, methanol and then ethanol, and dried to provide 1.7 g of 2-(p-carboxyphenyl)imidazo[2,1-b]benzothiazole.
