실험 절차

A solution of 0.300 g (1.65 mmol) of the 1:1 mixture of the 3-chloro-6-ethyl-5-methyl-pyrazine-2 -carbonitrile and the 3-chloro-5-ethyl-6-methyl-pyrazine-2-carbonitrile, of 0.395 g (1.30 mmol) of 2,3,4,5-tetrahydro-1H-benzo[d]azepine hydrochloride (J. Heterocycl. Chem. 1971, 8(5), 779-83) and of 0.566 g (2.60 mmol) of N-ethyl-diisopropylamine in 1.0 ml of N,N-dimethylformamide was stirred at room temperature for 60 hours and then at 60° C. for 18 hours. The reaction mixture was subsequently poured into 50 ml of an ice/water mixture and extracted 3 times with 50 ml of ethylacetate. The combined ethylacetate phases were dried over magnesium sulfate and evaporated under reduced pressure. The residue formed was then chromatographed on silica gel using dichloromethane as eluent giving 0.086 g (0.29 mmol, 18% of theory) of the 6-ethyl-5-methyl-3-(1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-pyrazine-2-carbonitrile as yellowish solid after crystallization from dichlormethane/pentane; MS: 293 (M+H)+; and 0.074 g (0.25 mmol, 15% of theory) of the 5-ethyl-6-methyl-3-(1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-pyrazine-2-carbonitrile as yellowish solid; MS: 293 (M+H)+.
