Pentamethylbenzene → HCID 72303454, compound

Participants

Reaction Steps

A solution of 400 mg of (3RS,4RS)-6-(benzyloxy)-3-(2,4-dichlorophenyl)-2-{(1SR,2SR)-2-[(methylsulfonyl)amino]cyclohexyl}-1-oxo-N-(pyridin-2-ylmethoxy)-1,2,3,4-tetrahydroisoquinoline-4-carboxamide and 245 mg of pentamethylbenzene in 15 ml of trifluoroacetic acid was stirred at room temperature overnight. The trifluoroacetic acid was evaporated under reduced pressure, and ethyl acetate and water were added thereto to carry out a liquid separation operation. The organic layer was washed with a saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, and then evaporated under reduced pressure. The residue was solidified with ethyl acetate-isopropyl alcohol and collected by filtration to obtain 350 mg of (3RS,4RS)-3-(2,4-dichlorophenyl)-6-hydroxy-2-{(1SR,2SR)-2-[(methylsulfonyl)amino]cyclohexyl}-1-oxo-N-(pyridin-2-ylmethoxy)-1,2,3,4-tetrahydroisoquinoline-4-carboxamide as a white solid.
