Procedure

A mixture of 17 (1.70 g, 5.0 mmol) and 10% Pd/C (85 mg) in EtOAc (70 mL) was hydrogenated in a Parr under H2 at 42 psi for 15 h. The mixture was filtered through Celite and the filtrate was concentrated in vacuo. Chromatography on silica (50-60% EtOAc/hexanes) gave 1.70 g (100%) of a colorless oil. 1H NMR (CDCl3, 300 MHz) 8.54 (d, J=2.0 Hz, 1H), 8.48 (dd, J=4.8, 1.5 Hz, 1H), 7.70-7.10 (m, 6H) 4.58 (s, 2H), 3.31 (t, J=7.3 Hz, 2 H), 3.09 (t, J=7.4 Hz, 2H), 1.50 (s, 9H); 13C NMR (CDCl3, 75MHz) 198.3, 168.0, 158.6, 150.4, 148.1, 138.4, 136.9, 136.4, 130.2, 123.7, 121.8, 120.7, 113.5, 83.0, 66.1, 40.2, 28.4, 27.5.
