Participants

Reaction Steps

A solution of the compound obtained in Example 496 (250 mg) and 6N hydrochloric acid (4 mL) in THF (4 mL) was stirred at 80° C. for 14 hr. The reaction mixture was made basic with 8N aqueous sodium hydroxide solution, and the resultant product was extracted with ethyl acetate. The organic layer was dried, and the solvent was evaporated under reduced pressure to give crude 4-chloro-N-[(3R,4R)-3-(3,4-dichlorophenyl)-1-(piperidin-4-ylsulfonyl)piperidin-4-yl]-N-methylbenzamide as a colorless oil.
