Potassium Carbonate → HCID 57595521, compound

Participants

Reaction Steps

Methyl 5-{[(2S,4R)-4-[acetyl(4-chlorophenyl)amino]-2-methyl-3,4-dihydroquinolin-1(2H)-yl]carbonyl}thiophene-2-carboxylate (80 mg, 0.17 mmol, 1 eq.) was dissolved in methanol (6 ml). A solution of potassium carbonate (200 mg, 1.4 mmol, 8 eq.) in water (2 ml) was added and reaction mixture was stirred at room temperature for 20 h. The mixture was concentrated and the residue was acidified with a 1N HCl aqueous solution and extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulfate, filtered and concentrated to give 5-{[(2S,4R)-4-[acetyl(4-chlorophenyl)amino]-2-methyl-3,4-dihydro-quinolin-1(2H)-yl]carbonyl}thiophene-2-carboxylic acid (76 mg, 99%).
