Sodium ethoxide → HCID 58585859, compound

Participants

Reaction Steps

4-Chloro-3-methanesulfonyl-quinoline-6-carboxylic acid ethyl ester (example 61f, 7.96 g, 25.4 mmol) was dissolved in anhydrous alcohol (500 mL) which containing sodium ethoxide (3.45 g, 50.8 mmol). The mixture was heated at 60 degrees for 6 hours under stirring. After the reaction, the solvent was evaporated under reduced pressure, and then dichloromethane was added. After filtration, the filtrate was concentrated to give 4-ethoxy-3-methanesulfonyl-quinoline-6-carboxylic acid ethyl ester, which was used for next step without further purification. LC-MS m/e 324 (MH+).
