Procedure

To a suspension of N-[4—(3-hydroxypyridin-2-ylmethyl)phenyl]-7—(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (400 mg) in tetrahydrofuran (30 ml) was added 3-chloroperbenzoic acid (70%, 0.32 g) at 0° C., and the mixture was stirred at room temperature for 15 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, concentrated under reduced pressure and recrystallized from ethanol to give N-[4—(1-oxido-3-hydroxypyridin-2-ylmethyl)phenyl]-7—(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 175) (262 mg) as pale yellow crystals.
