Versuchsvorschrift

To a solution of 6-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)pyridin-3-ol (0.260 g) in tetrahydrofuran (10 mL) were added cyclopropylmethanol (83 mg), tributylphosphine (0.29 mL) and 1,1′-(azodicarbonyl)dipiperidine (290 mg), and the mixture was stirred at room temperature for 16 hr. The reaction mixture was concentrated under reduced pressure, the residue was dissolved in toluene (10 mL), and hexane (10 mL) was added. The obtained suspension was filtered to remove the precipitate, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=20:80-70:30, volume ratio) to give the title compound (0.240 g, yield 83%) as a colorless amorphous solid. MS: 507 (MH+).
