実験手順

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 2-chlorophenylboronic acid (CAS RN 1679-18-1) and using a gradient of n-heptane:EtOAc (100:0 to 30:70) for the chromatographic purification. Colorless oil (69%). MS (ESI): m/z=403.012 [M+H]+.
