Reaction Steps

Add methylpropylamine (0.21 mL, 2.0 mmol) to a suspension of 2-chloro-6-methanesulfonyl-isonicotinic acid methyl ester (0.25 g, 1.0 mmol), palladium acetate (0.022 g, 0.1 mmol), racemic 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (0.062 g, 0.1 mmol), and cesium carbonate (0.325 g, 1.0 mmol) in toluene (5 mL) at room temperature and stir 18 h at 80° C. Cool, filter through a filtering agent and purify (silica gel chromatography, eluting with 20:80 to 40:60 ethyl acetate:hexanes) to give the title compound (0.181 g, 63%).
