Reaction Steps

A solution of 130 mg (0.66 mmol) of 4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride in 5 ml of dioxane was treated at room temperature with 0.23 ml (1.32 mmol) of N-ethyl-diisopropylamine and, thereupon, with 112 mg (0.60 mmol) of crude 5-chloro-3-methylsulfanyl-[1,2,4]triazine-6-carbonitrile. The reaction mixture was stirred at 50° C. during 18 hours. For the working-up, the solution was evaporated under reduced pressure and the residue was chromatographed on silica gel with a 2:1 mixture of hexane and ethylacetate as the eluent. There were obtained 120 mg (0.34 mmol, 64.5% of theory) of 3-methylsulfanyl-5-(4-phenyl-3,6-dihydro-2H-pyridin-1-yl)-[1,2,4]triazine-6-carbonitrile in the form of an orange powder; MS: [M+H]+=310.
