Versuchsvorschrift

To a solution of 5-hydroxy-2-[(phenylmethyl)oxy]-N-3-pyridinylbenzamide (may be prepared as described in Example 44; 200 mg, 0.62 mmol) in dimethylsulfoxide (8 ml) was added sodium hydride (17.98 mg, 0.75 mmol) at 0° C., and the mixture was stirred at room temperature for 1 h. 2-[{[(1,1-Dimethylethyl)oxy]carbonyl}(methyl)amino]ethyl 4-methylbenzenesulfonate (247 mg, 0.75 mmol) in dimethylsulfoxide (8 ml) was added to the solution dropwise, and the mixture was stirred at 75° C. for 18 h. The mixture was poured into water (100 ml), extracted thoroughly with ethyl acetate. The organic layer was dried, and concentrated to obtain a crude product. The crude product was purified by chromatography on silica gel (dichloromethane/methanol=15:1) to yield the title compound as a yellow oil. 140 mg.
