Reaction Steps

A solution of 2-amino-1,3-benzthiazole (40 mg, 0.27 mmol) in methylene chloride (1 ml) and pyridine (100 μl) was treated with 4-n-butylbenzoyl chloride and stirred at 25° C. for 30 minutes. After this time, the reaction was treated with NaOH (0.5 ml, 5.0 M) and the resulting mixture stirred overnight. The resulting precipitate was collected by filtration and recrystallized from water to give 2-(4-n-butylbenzamido)-1,3-benzthiazole as pale yellow needles. (47 mg, 53%)
