Reaction Steps

Example 9 was prepared by coupling 4-methyl-3-[4-(2-methyl-pyridin-3-yl)-[1,2,3]triazol-1-yl]-benzoic acid (5:3 mixture with 4-methyl-3-[5-(2-methyl-pyridin-3-yl)-[1,2,3]triazol-1-yl]-benzoic acid) with N-(3-amino-5-tert-butyl-2-methoxy-phenyl)-methane-sulfonamide in the same manner as Example 1. Preparative HPLC was used to separate N-(5-tert-butyl-3-methanesulfonylamino-2-methoxy-phenyl)-4-methyl-3-[4-(2-methyl-pyridin-3-yl)-[1,2,3]triazol-1-yl]-benzamide from N-(5-tert-Butyl-3-methanesulfonylamino-2-methoxy-phenyl)-4-methyl-3-[5-(2-methyl-pyridin-3-yl)-[1,2,3]triazol-1-yl]-benzamide. ESI MS m/z 549 [C28H32N6O4S+H]+.
