2H-1-Benzopyran-2-carboxylic acid, 6-fluoro-3,4-dihydro-, ethyl ester

It often serves to produce the 6-fluoro-3,4-dihydro-2H-1-benzopyran-2-carboxaldehyde, which is subsequently converted into the oxirane intermediate essential for forming the final, complex molecule of Nebivolol. Ethyl 6-fluoro-3,4-dihydro-2H-1-benzopyran-2-carboxylate is a critical key intermediate used in the industrial synthesis of Nebivolol, a third-generation selective beta1-blocker.
