実験手順
Phenylmethyl 5-chloro-2-[(phenylmethyl)oxy]benzoate (may be prepared as described in Description 43; 4.16 g, 11.8 mmol), in ethanol (40 ml) and 2M NaOH (20 ml) was heated at reflux for two hours. The mixture was cooled, concentrated in vacuo, acidified with 2M HCl and extracted with ethyl acetate (×3). The organics were washed with brine, dried (MgSO4), and concentrated to give a yellow oil. Purified using biotage chromatography (C18 cartridge, CH3CN/H2O) to give the title compound as a white solid. 1.9 g.
