4-Chloro-2-methoxy-1-nitro-benzene (1.12 g, 5.96 mmol), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (1.84 g, 5.95 mmol), tetrakis(triphenylphosphine)palladium(0) (380 mg, 0.33 mmol), a 2 M solution of potassium bicarbonate in water (7.45 mL, 14.9 mmol), and 1,4-dioxane (18 mL) were combined in a sealed tube, and the mixture was stirred and heated at 80° C. overnight. HPLC indicated the complete conversion of the starting material. The product, 4-(3-methoxy-4-nitro-phenyl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester was isolated by flash chromatography (Silicagel, EtOAc/Hexanes 25-50%) in 90% yield.
