Yield:33626-98-1 100%

Reaction Conditions:

with sulfuric acidReflux;

Steps:

2 Synthesis of S7

6-Bromo-2-naphthalenecarboxylic acid (2.4996 g, 10.0 mmol) was added50mL dried egg-shaped flask, add 20mL of anhydrous methanol to dissolve,Then 1 mL of concentrated sulfuric acid was slowly added dropwise and the system was refluxed overnight.TLC tracking until the conversion of raw materials is completed, stop heating,After cooling to room temperature, saturated aqueous sodium carbonate solution was added to quench the reaction.The reaction system was adjusted to neutrality, extracted with ethyl acetate,The organic phase is washed three times with anhydrous sodium sulfate.Concentration under reduced pressure afforded S7 (2.63 g, 100% yield) as a white solid.
