Triethylamine → ({2-[(2,6-Dichlorobenzoyl)amino]-3-[2-(2,6-dichlorophenyl)-6-quinolinyl]propanoyl}oxy)methyl pivalate

Participants

Reaction Steps

To 2-[(2,6-dichlorobenzoyl)amino]-3-[2-(2,6-dichlorophenyl)-6-quinolinyl]propanoic acid 38 (534 mg) are added 195 μl of triethylamine and, after 15 minutes, 290 μl of chloromethyl pivalate. The solution is stirred at RT overnight and then poured in AcOEt. The organic phases are washed with water and brine, dried over MgSO4 and concentrated. The resulting residue is purified over silica gel using CH2Cl2/C2H5OH 99/1 as eluent to give ({2-[(2,6-dichlorobenzoyl)amino]-3-[2-(2,6-dichlorophenyl)-6-quinolinyl]propanoyl}oxy)methyl pivalate 129.
