Preparation of example 122 from the title compound of Example 7 (100 mg, 0.362 mmol), 2-(toluene-4-sulfonylamino)-benzoic acid (158 mg, 0.542 mmol), triethylamine (0.201 mL, 1.446 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (206 mg, 0.542 mmol) in N,N-dimethylformamide (4.0 mL) was carried out analogously to Example 11. When the reaction was judged complete, N,N-dimethylformamide was evaporated and methanol was added. The mixture was filtered and the solids collected and washed with methanol, dichloromethane and diethyl ether. After drying under vacuum, the title compound (121 mg, 0.220 mmol) was obtained as a yellow powder in 61% yield.
