Reaction Steps

Phenylacetonitrile (8.1 g, 69 m mol) was added to a room temperature solution of potassium hydroxide (85%) (74 g, 1.1 mol) in methanol (150 ml). To this was added 4-bromo-1-nitrobenzene (12.7 g, 63 m mol) suspended in methanol (130 ml). An exotherm was noted and the reaction was maintained at 50° C. for 5 hrs. After cooling to room temperature, water (400 ml) was added. The precipitate was collected and washed with water. The crude product (13.15 g) was crystallized from hot methanol (200 ml) to yield yellow needles (9.52 g, mp 113°-116° C.).
