Triethylamine → Ethyl [4-({butyl[2-methyl-4'-(trifluoromethyl)-1,1'-biphenyl-3-yl]amino}sulfonyl)-2-methylphenoxy]acetate

Participants

Reaction Steps

To a solution of N-butyl-N-[2-methyl-4′-(trifluoromethyl)-1,1′-biphenyl-3-yl)amine (58 mg, 0.19 mmol) in anhydrous CH2Cl2 (5 mL) was added ethyl [4-(chlorosulfonyl)-2-methylphenoxy]acetate (83 mg, 0.28 mmol) and triethylamine (0.052 mL, 0.38 mmol). The resulting solution was stirred 20 h at room temperature under nitrogen. The reaction was diluted with CH2Cl2 (50 mL), and the organic solution washed with aq. sat. NaHCO3 (10 mL) and brine (10 mL). The organic extract was separated by hydrophobic frit and evaporated. Purification by mass directed autoprep afforded the title compound as a colourless oil (15 mg).
