3-Fluorobenzenesulfonyl Chloride → HCID 67440735, compound

Participants

Reaction Steps

To a stirred solution of methyl 2-(2-aminophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (1.0 g, 3.22 mmol, 1.0 eq.) in pyridine (5 mL) and dichloro methane (20 mL) at 0° C. was dropwise a solution of 3-fluorobenzene-1-sulfonyl chloride (940 mg, 4.83 mmol, 1.5 eq.) in dichloromethane (30 mL). The mixture was stirred at room temperature for 6 h. Thin layer chromatography and LC-MS showed reaction completed. The mixture was quenched with 50 mL water and extracted with ethyl acetate (100 mL×3). The combined organic layers were dried over anhydrous sodium sulfate and evaporated to afford 1.987 g of methyl 2-(2-(3-fluorophenylsulfonamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (pyridine included) as light yellow solid, which was used in next step without further purification.
