To a solution of (S)-methyl 2-(2-chloro-6-vinylpyrimidine-4-carboxamido)propanoate (0.444 g, 1.65 mmol) in dioxane (10 mL) was added 2-(4-(4-fluorophenoxy)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.521 g, 1.66 mmol), 2M aqueous Na2CO3 (1.65 mL, 3.30 mmol), and PdCl2(dppf) (0.071 g, 0.087 mmol). The reaction vessel was flushed with argon, sealed and heated at 100° C. overnight. After cooling, the reaction mixture was evaporated in vacuo and the residue chromatographed over silica gel with 10-40% EtOAc in hexanes. The product fractions were evaporated in vacuo to give (S)-methyl 2-(2(4-(4-fluorophenoxy)phenyl)-6-vinylpyrimidine-4-carboxamido)propanoate as a tan-yellow oil (0.304 g, 0.72 mmol, 44% yield). LC/MS: m/z=422.2 [M+H]+.
