Purge a mixture of 1-(4-bromo-2,6-dichloro-benzyl)-3-piperidin-1-yl-pyrrolidin-2-one (0.150 g, 0.37 mmol) and 4-fluorophenylboronic acid (0.150 g, 1.07 mmol) in toluene (7 mL) and 2M sodium carbonate (1.3 mL) with N2. Treat the reaction with Pd(PPh3)4 (0.043 g, 0.037 mmol) and heat to 90° C. for 4 hours under N2. Cool the reaction, dilute with ethyl acetate, and wash with and water. Dry the organic layer (Na2SO4), remove the solvent in vacuo to afford crude product, and purify with a 0 to 10% methanol in CH2Cl2 gradient to afford 0.050 g (32%) of the titled product. Rf=0.46 (9/1 CH2Cl2/methanol). ES MS (m/z): 421 (M+).
