Participants

Reaction Steps

After 0.58 g of 6,11-dihydro-N-(2,6-diisopropylphenyl)-2-methoxycarbonyldibenz[b,e]oxepin-11-carboxamide (Compound 24) obtained in Example 24 was dissolved in 24 ml of methanol, 6 ml of 5 N sodium hydroxide was added to the solution. The mixture was heated under reflux for 5 minutes. After completion of the reaction, the mixture was cooled to room temperature and 4N hydrochloric acid was added thereto to adjust pH to 3. The mixture was extracted with ethyl acetate. After washing with saturated sodium hydroxide aqueous solution, the organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure to dryness to obtain 0.52 g of Compound 25.
