titleOfInvention | METHODS OF FORMATION OF PINACOLIC ESTERS OF ACID 4-CHLORINE-2-FLUORO-3-SUBSTITUTED-PHENYLBORONIC AND ITS METHODS OF USE |
abstract | The methods include the formation of pinacolic esters of 4-chloro-2-fluoro-3-substituted-phenylboronic acid. The method comprises contacting a 1-chloro-3-fluoro-2-substituted-benzene with an alkyl lithium to form a lithium-1-chloro-3-fluoro-2-substituted-benzene. The lithium-1-chloro-3-substituted-benzene-lithium is contacted with an electrophilic boronic acid derivative to form a 4-chloro-2-fluoro-3-substituted-phenylboronate. The 4-chloro-2-fluoro-3-substituted-phenylboronate is reacted with an aqueous base to form a (4-chloro-2-fluoro-3-substituted-phenyl) trihydroxyborate, the (4-chloro-2-fluoro -3-substituted-phenyl) trihydroxyborate is reacted with an acid to form a 4-chloro-2-fluoro-3-substituted-phenylboronic acid. 4-Chloro-2-fluoro-3-substituted-phenylboronic acid is reacted with 2,3-dimethyl-2,3-butanediol to form pinacolic esters of 4-chloro-2-fluoro-3-substituted-phenylboronic acid. Methods of using 4-chloro-2-fluoro-3-substituted-phenylboronic acid pinacolic esters to produce 6- (4-chloro-2-fluoro-3-substituted-phenyl) -4-aminopicolinates are also described. |
