Participants

Reaction Steps

To a solution of N-[4—(3-methoxymethoxypyridin-2-ylmethyl)phenyl]-7—(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (1.00 g) in ethanol(20 ml) was added concentrated hydrochloric acid (5.0 ml), and the mixture was stirred at room temperature for 4 days. To the mixture was added saturated sodium bicarbonate solution at 0° C. to make the solution pH 6-7, and precipitated crystal was collected by filtration to give N-[4—(3-hydroxypyridin-2-ylmethyl)phenyl]-7—(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 174) (693 mg) as pale yellow crystals.
