実験手順
To a solution of fluoro-diphenyl-acetic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl) ester [Example 109(i)] (0.034 g, 0.1 mmol) in DMSO (0.25 ml) is added bromo-acetic acid phenyl ester (0.071 ml, 0.5 mmol). The reaction mixture is left standing at room temperature overnight. Purification is carried out by chromatography on C18 silica, eluting with water:acetonitrile to yield the titled compound as a colourless oil.
