Reaction Steps

2-(5-Chloro-1H-benzimidazol-2-yl thio)nitrobenzene (0.3 g) was dissolved in dry ethanol (100 ml) with warming and the solution was hydrogenated in the presence of 10% Pd/C at 3 atmospheres pressure and 50° for 2.75 hours. The heating and stirring were stopped and the mixture was left standing under an H2 atmosphere overnight. The mixture was then filtered through a filter aid and evaporated under reduced pressure, and dried under vacuum at 50° to leave the sub-title compound as a pale greenish glassy solid (0.23 g), mp 155°-156°.
