Hydrochloric Acid → 3-[2-(2,6-dichlorophenyl)-6-quinolinyl]-2-[({(2S)-1-[(4-methylphenyl)sulfonyl]piperidinyl}carbonyl)amino]propanoic acid

Participants

Reaction Steps

To 455 mg of methyl 3-[2-(2,6-dichlorophenyl)-6-quinolinyl]-2-[({(2S)-1-[(4-methylphenyl)sulfonyl]piperidinyl}carbonyl)amino]propanoate 46 in CH3OH (5 ml) are added 0.8 ml of 1 N NaOH and 1 ml of water. The solution is stirred at RT overnight, and 1 N HCl (0.8 ml) is added to obtain a weakly acidic pH. Methanol is then evaporated, and the solid obtained is filtered, washed with water and dried to give 3-[2-(2,6-dichlorophenyl)-6-quinolinyl]-2-[({(2S)-1-[(4-methylphenyl)sulfonyl]piperidinyl}carbonyl)amino]propanoic acid 90.
