Procedure
In analogy to the procedure as described in example 12 the 2-chloro-3-cyanopyrazine (J. Chem. Soc., Perkin Trans. 1 1991, 11, 2877-81) was treated with 2,3,4,5-tetrahydro-1 H-benzo[d]azepine hydrochloride (J. Heterocycl. Chem. 1971, 8(5), 779-83) and N-ethyl-diisopropylamine in N,N-dimethylformamide at room temperature followed by 60° C. to yield the 3-(1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-pyrazine-2-carbonitrile as light yellow solid; MS: 251 (M+H)+.
Workup
- customfollowed by 60° C.
