Reaction Steps

52 mg tetrakis(triphenylphosphine) palladium was added to 100 mg 2-chloropyridine, 327 mg 4-(4,4,5,5-tetramethyl-(1,3,2)dioxaborolan-2-yl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester and 0.88 mL 2 mol/L sodiumcarbonate in 2 mL dioxane. The reaction was stirred for 15 min. at 140° C. in a microwave. Water was added and the reaction was extracted with DCM. The organic layer was dried and evaporated. The residue was purified by HPLC to yield 116 mg of the desired product. Rt: 1.03 min (method L), (M+H)+: 261
