A solution of ethyl 3-(4-phenoxyphenyl)propanoate (S29, 500 mg, 1.95 mmol) in THF/MeOH (1/1, 8 mL) was treated with aqueous 4 N NaOH (0.5 mL) and was stirred for 20 h at 25° C. The reaction mixture was concentrated, diluted with aqueous 1 N HCl and extracted with CH2Cl2. The organic layer was dried over Na2SO4, filtered and concentrated to afford S30 (390 mg, 1.61 mmol, 82%) as a white solid: 1H NMR (CDCl3, 500 MHz) 7.34 (dd, 2H, J=8.4, 7.4 Hz), 7.18 (d, 2H, J=8.4 Hz), 7.10 (dt, 1H, J=7.7, 1.1 Hz), 7.00 (dd, 2H, J=8.8, 1.1 Hz), 6.95 (d, 2H, J=8.4 Hz), 2.96 (t, 2H, J=7.7 Hz), 2.70 (t, 2H, J=7.7 Hz); 13C NMR (CDCl3, 125 MHz) 179.2, 157.3, 155.6, 135.0, 129.7, 129.5, 123.1, 119.0, 118.7, 35.7, 29.8.
