General description

2,6-Difluorophenyl isothiocyanate (1,3-Difluoro-2-isothiocyanatobenzene), an aryl isocyanate, can be prepared from difluoroaniline. 1H-[1,2,4]triazole-3,5-diamine undergoes acylation with 2,6-difluorophenyl isothiocyanate to form the corresponding 1-acyl-1H-[1,2,4]triazole-3,5-diamine.

Structure-activity studies were carried out on a series of antihypertensive 1-(2-aminoethyl)-3-(substituted phenyl)thioureas. From this class of compounds, the 2,6-dichlorophenyl analogue 2 was found to have potent oral antihypertensive activity in two hypertensive rat models and the renal hypertensive dog. In
