Versuchsvorschrift

To a solution of the alcohol from step 2 (0.017 g, 0.137 mmol), 5-chloro-5'-(1-triphenylmethyl-1H-imidazol-4-ylmethyl)-[1,2']bipyridinyl-2-one from Example 23, Step 5 (0.0758 g, 0.143 mmol) and diisopropylethylamine (0.047 mL, 1.49 mmol) in dichloromethane (1.3 mL) at -78° C. was added trifluoromethanesulfonic anhydride (0.023 mL, 0.136 mmol) and the mixture stirred at -78° C. for 1 hour. The mixture was allowed to warm to 0° C. and stirred for 2 hours. The solvent was evaporated in vacuo. The residue was dissolved in methanol (1 mL), heated at reflux for 2 hour, and the solvent evaporated in vacuo. The residue was partitioned between CH2Cl2 and sat. aq. NaHCO3 solution. The organic layer was dried, (Na2SO4) and the solvent evaporated in vacuo. The residue was chromatographed (Silica gel, 1:99 to 3:97 MeOH:CH2Cl2) to afford the title compound as a white solid.
