Procedure

To a dichloromethane (0.100 mL) solution of (±)-6-methoxy-2-methyl-4-phenyl-3-piperidin-3-ylisoquinolin-1(2H)-one (30 mg, 0.086 mmol) and N,N-diisopropylethylamine (0.017 mL, 0.095 mmol) was added benzoyl chloride (0.011 mL, 0.095 mmol). After 24 hours saturated sodium bicarbonate and additional dichloromethane were added. The layers were separated and the organic phase dried with anhydrous magnesium sulfate. Evaporation of the solvent in vacuo followed by trituration with ether-EtOAc gave a white solid which was isolated by vacuum filtration to give the titled product. ESI+MS: 453.3 [M+H]+.
