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

Participants

Reaction Steps

To a solution of N-(2-cyclopropylethyl)-N-[4′-(trifluoromethyl)-1,1′-biphenyl-3-yl]amine (155 mg, 0.51 mmol) in anhydrous CH2Cl2 (10 mL) under nitrogen at room temperature was added ethyl [4-(chlorosulfonyl)-2-methylphenoxy]acetate (223 mg, 0.76 mmol) and triethylamine (0.213 mL, 1.53 mmol). The resultant mixture was stirred for 40 h at room temperature. The reaction mixture was diluted with water (15 mL) and extracted with CH2Cl2 (30 mL). The organic solution was passed through a hydrophobic frit and the solvent was removed in vacuo. Purification by Biotage™ chromatography (40 g Silica column) eluted with 1:19–1:9 EtOAc:cyclohexane afforded the title compound as a white crystalline solid (156 mg).
