実験手順

Another embodiment of the present disclosure includes a method of forming 2-(4-chloro-2-fluro-3-methoxylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane that comprises contacting 2-chloro-6-fluoroanisole with n-butyl lithium to form 6-chloro-2-fluoro-3-lithioanisole. The 6-chloro-2-fluoro-3-lithioanisole may be contacted with trimethyl borate to form dimethyl 4-chloro-2-fluoro-3-methoxyphenylboronate. The dimethyl 4-chloro-2-fluoro-3-methoxyphenylboronate may be reacted with aqueous potassium hydroxide to form potassium (4-chloro-2-fluoro-3-methoxyphenyl)trihydroxyborate. The potassium (4-chloro-2-fluoro-3-methoxyphenyl)trihydroxyborate then may be reacted with aqueous hydrochloric acid to form 4-chloro-2-fluoro-3-methoxyphenylboronic acid. The 4-chloro-2-fluoro-3-methoxyphenylboronic acid may be reacted with 2,3-dimethyl-2,3-butanediol.
