実験手順

To a degassed solution of 2-(4-hydroxy-phenyl)-morpholine-4-carboxylic acid tert-butyl ester (10.23 g; 36.6 mmol), and 1-iodo-2,3-dimethyl-benzene (10.62 g; 45.8 mmol) in DMSO (50 mL), was added picolinic acid (0.90 g; 7.3 mmol), CuI (0.70 g; 3.7 mmol) and K3PO4 (15.55 g; 73.3 mmol). The resulting mixture was heated overnight, at 90° C. After cooling to RT, brine was added and the mixture extracted with CH2Cl2. The combined organic layers were dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by column chromatography (SiO2, CH2Cl2) to afford 2-[4-(2,3-dimethyl-phenoxy)-phenyl]-morpholine-4-carboxylic acid tert-butyl ester.
