실험 절차

To a solution of methyl 4-((2S,4R)-1-acetyl-4-((isopropoxycarbonyl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)benzoate (for a preparation see Intermediate 19) (1.63 g, 3.84 mmol) in methanol (20 mL) was added lithium hydroxide (4.61 mL, 4.61 mmol). The resulting mixture was stirred at 40° C. for 6 h, whereupon it was concentrated under reduced pressure to give lithium 4-((2S,4R)-1-acetyl-4-((isopropoxycarbonyl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)benzoate (1.65 g, 100%) which was not purified but directly used in the subsequent step. LCMS (Formate, 2 min), Rt=0.87, MH+=411.
