실험 절차

The title compound is prepared from 3-bromo-pyridine-2-carboxylic acid and 2-(3-methoxy-2-methyl-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (may be prepared as in WO 2001053268 described) following the synthetic sequence and protocols described for Intermediate 41; since 3-bromo-pyridine-2-carboxylic acid instead of 3-bromo-pyridine-2-carbonitrile is used for the Suzuki-Miyaura coupling (Step 1 of Intermediate 41), hydrolysis of the nitrile (Step 2 of Intermediate 41) is omitted.
