Participants

Reaction Steps

To a solution of 7-(4-ethoxyphenyl)-N-[4-[N-(4,4-ethylenedioxycyclohexyl)-N-methylaminomethyl]phenyl]-2,3-dihydro-1-benzoxepine-4-carboxamide (151.5 mg) in THF (10 ml) was added at room temperature 3N hydrochloric acid (2 ml), and the mixture was stirred for 22 hours. To the mixture was added saturated sodium bicarbonate solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried with magnesium sulfate. Under reduced pressure, the mixture was concentrated to give colorless solid, which was recrystallized from ethyl acetate/diisopropylether to give colorless crystals of 7-(4-ethoxyphenyl)-N-[4-[N-methyl-N-(4-oxocyclohexyl)aminomethyl]phenyl]-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 288) (103.5 mg).
