실험 절차
3-Chloro-2-(4-chlorobenzyl)-3-(4-chlorophenyl) isoindolin-1-one (157 mg, 0.390 mmol) was reacted with 1,3-cyclopentanediol (0.18 mL, 1.95 mmol.) as for general procedure C and the solvent evaporated under vacuum to leave a clear oil of crude 2-(4-chlorobenzyl)-3-(4-chlorophenyl)-3-(3-hydroxycyclopentyloxy)isoindolin-1-one. This was purified by HPLC to give the pure product which was a clear glass (83 mg, 0.177 mmol., 45%). Rf 0.08 (40:60 EtOAc:petrol). λmax (CH3OH)/nm=220.5 (Abs=1.333).
