Participants

Reaction Steps

To a mixture of 200 mg of N-[4-(benzyloxy)phenyl]-2-{[3-(morpholin-4-ylmethyl)benzoyl]amino}-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide and 6.0 mL of TFA was added 255 mg of 1,2,3,4,5-pentamethylbenzene, followed by stirring overnight at room temperature. The reaction mixture was concentrated under reduced pressure, and ethyl acetate and a saturated aqueous sodium hydrogen carbonate solution were added thereto, followed by extraction using ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (3% methanol/chloroform), thereby obtaining 169 mg of N-(4-hydroxyphenyl)-2-{[3-(morpholin-4-ylmethyl)benzoyl]amino}-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide.
