Versuchsvorschrift

Purge a mixture of 1-(4-bromo-2,6-dichloro-benzyl)-3-piperidin-1-yl-pyrrolidin-2-one (0.429 g, 1.06 mmol) and 4-methoxycarbonyl phenylboronic acid (0.57 g, 3.16 mmol) in toluene (15 mL) and 2M sodium carbonate (3.7 mL) with N2. Treat the reaction with Pd(PPh3)4 (0.061 g, 0.053 mmol) and heat to 90° C. for 7 hours under N2. Cool the reaction, dilute with ethyl acetate, and wash with water. Dry the organic layer (Na2SO4), remove the solvent in vacuo afford crude product, and purify with a 0 to 10% methanol in CH2Cl2 gradient to afford 0.19 g (39%) of the titled product. Rf=0.40 (9/1 CH2Cl2/methanol). ES MS (m/z): 461 (M+).
