Procedure

To a solution of N-[4-[hydroxy-(3-methoxypyridin-2-yl)methyl]phenyl]-7-(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (350mg) in tetrahydrofuran (30 ml) was added 3-chloroperbenzoic acid (70%, 0.26 g) at 0° C., and the mixture was stirred at room temperature for 64 hours. To the mixture was added sodium thiosulfate, and the mixture was stirred for a few minutes and extracted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate solution and saturated sodium chloride solution, dried with magnesium sulfate and concentrated under reduced pressure. The residue was separated and purified with column chromatography (ethyl acetate→ethanol/ethyl acetate=1:4) recrystallized from tetrahydrofuran-hexane to give N-[4-[hydroxy(3-methoxy-1-oxidopyridin-2-yl)methyl]phenyl]-7-(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 170) (168mg) as colorless crystals.
