Reaction Steps
To a solution of (R)-ethyl 6-iodo-4-oxo-1-(pyrrolidin-3-yl)-1,4-dihydroquinoline-3-carboxylate (Intermediate 110, 282 mg, 0.68 mmol, 1 equiv.) in THF (7 mL) was added iodomethane (0.0471 mL, 0.75 mmol, 1.1 equiv.) followed by potassium carbonate (378 mg, 2.74 mmol, 4 equiv.). This was stirred at 60° C. for 1 d. The reaction mixture was cooled to room temperature and partitioned between ethyl acetate (10 mL) and water (10 mL). The aqueous layer was extracted with ethyl acetate (2×10 mL), and the organics were concentrated to provide (R)-ethyl 6-iodo-1-(1-methylpyrrolidin-3-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate as a light yellow solid (282 mg, >99%).
