Procedure
The title compound was prepared in analogy to example 72, from (4-iodo-pyridin-3-yl)-methyl-amine (example 36, intermediate b) and 2-cyclopropoxyphenylboronic acid after stirring at 90° C. for 18 hours. The compound was purified by silica gel chromatography on a 20 g column using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). Light yellow oil (94%). MS (ESI): m/z=241.134 [M+H]+.
