Versuchsvorschrift
The title compound was prepared from (5-bromo-pyridin-2-yl)-acetonitrile and 1,3-dibromopropane following a procedure analogous to that described in Step 1 for Intermediate 34; additionally, 7-bromo-3,4-dihydro-2H-quinolizine-1-carbonitrile was obtained {Yield: 75% of theory; LC (method 1): tR=1.72 min; Mass spectrum (ESI+): m/z=237/239 (Br) [M+H]+}. Yield: 25% of theory; LC (method 1): tR=1.86 min; Mass spectrum (ESI+): m/z=237/239 (Br) [M+H]+.
