Abstract

The title compound, 5, was prepared and found to be a potent diuretic in the rat. At 27 mg/kg, urine output was 250% of the saline control, and the excretion of electrolytes was similar to thy hydrochlorothiazide control. At 80 mg/kg, the potassium excretion was the same as the saline control, and the sodium and chloride excretions more than doubled. Several analogues were prepared and tested. Some show diuretic activity.
