Reaction Steps

A 200g (1.64 mol) portion of 2,4-toluenediamine, 162g (1.23 mol, 2,45 equiv) of dicyclopentadiene, 200g (2.78 mol) of pentane, and 20.0g of an amorphous alumina-silica catalyst comprised of 13% alumina and 87% silica were charged to a 1000cc pressure vessel equipped with a mechanical stirrer. The vessel was sealed and purged with nitrogen leaving a 32 psig nitrogen blanket. The vessel contents were heated to 205° C. with stirring and were maintained at that temperature for 22 hours. The contents were cooled to 150° C. and isolated catalyst free by hot filtration. Selective removal of residual hydrocarbons by vacuum distillation and analysis by gas chromatography (GC) provides the following product mixture.
