Reaction Steps
1-Cyclopropylmethyl-piperazine (13 g, 94 mmol) was mixed with 4-(6-chloro-pyridin-3-yl)benzonitrile (5 g, 23 mmol). The mixture was heated at 140° C. for 1.5 hours. The mixture was cooled to rt and purified by column chromatography (EtOAc:petrolether=1:1) on silica gel to give 2.7 g (43%) of 4-[6-(4-cyclopropylmethyl-piperazin-1-yl)-pyridin-3-yl]-benzonitrile.
