Reaction Steps
This compound was prepared in a manner similar to that of 5-fluoro-2-methoxyphenylboronic acid (EXAMPLE 107) from 2-bromo-4-methylanisole (2.00 g, 9.94 mmol), n-BuLl (2.5M in hexanes; 4.00 mL, 10 mmol), and trimethylborate (3.4 mL, 30 mmol) to afford 1.60 g (96%) of 2-methoxy-5-methylphenylboronic acid which was used without further purification.
