Reaction Steps

Methyl 8-(3-(tert-butoxycarbonylamino)-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)-1-cyclopropyl-9-methyl-4-oxo-4H-quinolizine-3-carboxylate (43 mg, 0.083 mmol) was dissolved in methanol (2 mL) and sodium hydroxide 1M solution in water (0.5 mL, 0.5 mmol) was added. The mixture was stirred at 50° C. for 2 h. After cooling, the methanol was removed in vacuo. The residue was dissolved in water (5 mL) and then neutralized with 1M HCl (˜0.5 mL). The precipitate formed was stirred at room temperature overnight. The mixture was extracted with CH2Cl2 (3×4 mL). The organic layers were concentrated to afford the title compound as a yellow solid (29 mg, 69%). ESI-MS m/z: 504 (M+H)+.
