実験手順

A solution of (R)-3-(3-fluorophenoxy)-3-phenylpropyl chloride (0.971 g, 3.96 mmol), conc. NH4OH (30 mL), and EtOH (20 mL) were shaken at 90° C. on a Parr apparatus (50–90 psig) for 18 h. The mixture was then evaporated under vacuum and the residue was dissolved in Et2O (100 mL) and washed with H2O (2×25 mL). The organic layer was dried (anh. Na2SO4), filtered, and evaporated under vacuum to provide a yellow oil. This material was then dissolved in EtOAc (50 mL) and filtered. A solution of 30 maleic acid (0.272 g, 2.6 mmol, 0.93 equiv) dissolved in hot EtOAc (5 mL) was added to precipitate the maleate salt (519 mg, 53.5%) as a white solid: TLC Rf 0.25 (1% MeOH—CHCl3); GC, tr 7.37 min; MS, m/z 245 (M+). The synthesis of Compound 187 was accomplished as follows.
