실험 절차
The title compound was prepared in analogy to example 58, from N-(4-bromo-pyridin-3-yl)-N-methyl-3,5-bis-trifluoromethyl-benzamide (example 25, intermediate a) and 2-methoxy-3,4-difluorophenylboronic acid (CAS RN 905583-06-4) and using preparative HPLC for the chromatographic purification. Off-white solid (49%). MS (ESI): m/z=491.1 [M+H]+.
