Reaction Steps
A mixture of (S)-ethyl 2-(5-bromo-4-(4,4-dimethylpiperidin-1-yl)-2,6-dimethylpyridin-3-yl)-2-(tert-butoxy)acetate (0.02 g, 0.044 mmol), (3-fluoro-4-methylphenyl)boronic acid (0.014 g, 0.088 mmol) and 2M Na2CO3 (0.055 ml, 0.110 mmol) in DMF (1 mL) was degassed for 3 min. Then, Pd(Ph3P)4 (5.07 mg, 4.39 μmol) was degassed for 1 min and placed in a pre-heated oil bath at 90° C. After 9 h, cooled and purified by prep-HPLC to afford (S)-ethyl 2-(tert-butoxy)-2-(4-(4,4-dimethylpiperidin-1-yl)-5-(3-fluoro-4-methylphenyl)-2,6-dimethylpyridin-3-yl)acetate (0.0105 g, 0.022 mmol, 49.3% yield) as brown paste. LCMS (M+H)=485.3.
