Procedure

The title compound was prepared in analogy to example 72, from 4-iodo-N-((tetrahydro-2H-pyran-2-yl)methyl)pyridin-3-amine and 4-fluoro-2-methoxyphenylboronic acid after a reaction time of 3.5 hours at reflux. The compound was purified by silica gel chromatography on a 20 g column using an MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100) followed by EtOAc:MeOH (100:0 to 90:10). Brown oil (103%). MS (ESI): m/z=317.167 [M+H]+.
