Procedure
N-(4-chloro-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-2-methyl-6-(trifluoromethyl)nicotinamide (˜1 mmol) was used in Procedure A with 5-fluoro-2-bromopyridine (1 mmol). Purified by silica gel chromatography (5-45% ethyl acetate/hexanes) to yield N-(4-chloro-3-(5-fluoropyridin-2-yl)phenyl)-2-methyl-6-(trifluoromethyl)nicotinamide as a tan solid: MS (Q1) 409 (M)+.
