3,5-Bis(trifluoromethyl)phenyl isocyanate → 4-[3-(3,5-Bis(trifluoromethyl)phenyl)-1-(4-cyclohexylphenyl)ureidomethyl]benzoic acid methyl ester

Participants

Reaction Steps

4-((4-Cyclohexylphenylamino)methyl)benzoic acid methyl ester (2.38 g, 7.36 mmol) was dissolved in DCM (150 mL) and 3,5-bis(trifluoromethyl)phenyl isocyanate (1.36 mL, 8.10 mmol) was added and the mixture was stirred at room temperature for 16 hours. The reaction mixture was washed with water (3×15 mL), dried (magnesium sulphate) and concentrated in vacuo to afford 4.3 g of 4-[3-(3,5-bis(trifluoromethyl)phenyl)-1-(4-cyclohexylphenyl)ureidomethyl]benzoic acid methyl ester.
