Procedure

A mixture of 1′-{[1-(4-hydroxyphenyl)cyclopropyl]carbonyl}-3H-spiro[furo[3,4-c]pyridine-1,3′-pyrrolidin]-3-one (15 mg, purity: 80%, 0.034 mmol), (2-iodoethyl)-benzene (12 mg, 0.051 mmol), and tetra-n-butylammonium iodide (1 mg, 0.003 mmol), and Cesium Carbonate (28 mg, 0.086 mmol) in Dimethyl sulfoxide (0.3 ml) was stirred at r.t. overnight. Then the desired product was obtained from the mixture by prep-HPLC (0.24 mg). LCMS: m/z 455.1 (M+H)+; 477.0 (M+Na)+.
