Versuchsvorschrift

To a suspension of {3-[4-(4-cyclopropylbenzyloxy)-3-methoxyphenyl]-azetidin-1-yl}-(4-hydroxypyridin-2-yl)-methanone (0.45 g) prepared in a manner similar to Example (6) using 4-hydroxypyridine-2-calboxylic acid and K2CO3 (0.21 g) in DMF (8.0 mL) was added (R)-2,2-dimethyl-[1,3]dioxolan-4-ylmethyl toluene-4-sulfonate (0.33 g). The reaction mixture was stirred at 100° C. for 13 hr. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, and then dried over MgSO4. The solvent was removed under reduced pressure. The residue was purified by silica gel chromatography (Developing solvent: hexane/ethyl acetate=1/2) to give the title compound (0.27 g, 49%).
