Reaction Steps

The title compound was prepared in analogy to example 72, from (4-iodo-pyridin-3-yl)-(2,2,2-trifluoro-ethyl)-carbamic acid tert-butyl ester and (example 85, intermediate c) and 4,5-difluoro-2-methoxyphenylboronic acid (CAS RN 870777-32-5) and using a gradient of n-heptane:EtOAc (100:0 to 50:50) for the chromatographic purification. Colorless solid (79%). MS (ESI): m/z=419.139 [M+H].
