Intermediate 67: (5)-tert-butyl (1 -(5-(4-fl uoro-3-methylphenyl)pyridin-2-yI)ethyl)carbamate In a 5 mL microwave vial a solution of (5)-tert-butyl (1-(5-bromopyridin-2-yl)ethyl)carbamate(60 mg, 0.2 mmol), (4-fluoro-3-methylphenyl)boronic acid (37 mg, 0.24 mmol), Sodiumbicarbonate (0.2 mL, 0.4 mmol, 2 M aqueous solution) in Dioxane (2 mL) was bubbled N2 for 3mm then CI2Pd(dppf)CH2CI2 (16 mg, 0.02 mmol) was added. The capped tube was heated to100C for 16 h. After cooling the reaction mixture was diluted with EtOAc (10 mL) and washedwith water (10 mL). After separation, the aqueous phase was extracted with EtOAc (3 x 10 mL). Combined organics were dried over Na2504, filtered and concentrated. The crude material was purified through silica gel column chromatography (EtOAc in Heptane 12 to 100%) to give a white solid (66 mg, 80% yield). LCMS tR = 1.43 mm; MS m/z 331.1 (M+H).
