Procedure

The amide 13 (2.2 g, 4.3 mmol) was dissolved in THF (25 mL) and diluted with water (25 mL). Lithium hydroxide (0.41 g, 17.0 mmol) was added and the reaction mixture was stirred at room temperature for about 2 h. The THF was evaporated and the resulting aqueous layer was acidified with 2.0 M HCl and extracted into EtOAc (2×50 mL). The organic layer was washed with water (1×50 mL) and brine (1×50 mL), dried and concentrated to yield the desired acid compound 14 (2.0 g, 93.5%). 1H NMR (400 MHz, DMSO-d6): 12.1 (br, 1H), 7.20 (d, J=8.4 Hz, 2H), 7.17 (d, J=8.8 Hz, 2H), 7.14 (d, J=8.4 Hz, 1H), 6.86 (d, J=8.4 Hz, 2H), 6.82 (d, J=8.8 Hz, 2H), 4.52 (m, 1H), 3.22-3.47 (m, 8H), 2.72-2.80 (m, 4H), 1.28 (s, 9H).
