Versuchsvorschrift

The title compound was prepared from (6-bromo-pyridin-2-yl)-acetic acid ethyl ester and 1,2-dibromoethane following a procedure analogous to that described in Step 3 for Intermediate 4; under these conditions the ester group was hydrolyzed. Yield: 57% of theory; LC (method 3): tR=2.60 min; Mass spectrum (ESI+): m/z=242/244 (Br) [M+H]+.
