  • N-[4-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzoyl]-4-(trifluoromethylsulfonyl)aniline [ No CAS ]
YieldReaction ConditionsOperation in experiment
With triethylamine; In dichloromethane; Example 136 N-[4-(5,6-Dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzoyl]-4-(trifluoromethylsulfonyl)aniline 2-Chloro-1,3-dimethylimidazolinium chloride (130 mg, 0.77 mmol), 4-(trifluoromethylsulfonyl)aniline (173 mg, 0.77 mmol) and triethylamine (78 mg, 0.77 mmol) were added to a methylene chloride solution (8 ml) of 4-[(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl)-2-acetoxybenzoic acid (240 mg, 0.64 mmol) in a nitrogen atmosphere and the resulting solution was stirred for 2 hours. The reaction solution was diluted with chloroform, then washed with water and dried, and the solvent was removed by distillation. The residue was purified by silica gel column chromatography (methylene chloride: methanol = 60:1) to obtain the titled compound (146 mg, 0.251 mmol, 39percent).

With triethylamine; In dichloromethane; Example 173 N-[5-(5,6-Dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzoyl]-4-(trifluoromethylsulfonyl)aniline 4-(Trifluoromethylsulfonyl)aniline (0.452 g, 2.005 mmol), triethylamine (0.203 g, 2.005 mmol) and <strong>[37091-73-9]2-chloro-1,3-dimethylimidazolinium chloride</strong> (0.339 g, 2.005 mmol) were added to a methylene chloride solution (70 ml) of 5-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzoic acid (0.250 g, 0.668 mmol) and the resulting solution was stirred at room temperature for 12 hours. The reaction solution was poured into ice water and then extracted with methylene chloride. The extract was washed with water and then dried, and the solvent was removed by distillation. The obtained residue was purified by preparative thin-layer chromatography (chloroform: methanol = 10:1) and then recrystallized from ether to obtain the titled compound (0.140 g, 0.241 mmol, 36percent).

The reaction solution was poured into ice water and then extracted with methylene chloride. The extract was washed with water and then dried, and the solvent was removed by distillation. The obtained residue was purified by preparative thin-layer chromatography (chloroform: methanol = l and then recrystallized from ether to obtain the titled compound (0.084 g, 0.144 mmol, 27percent).
