Procedure
A solution of 260 (1.59 g, 2.47 mmol) in MeOH (142 ml) was treated with 10% Palladium on carbon (230.0 mg) and stirred under an atmosphere of H2 for 1.5 h. The mixture was filtered and the solvent evaporated to afford 1.04 g (100%) of a white foam. This was used in the next step without further purification: mp <40° C.; [α]D26 +1.6° (c 0.26, CH2Cl2); IR (KBr) 3422, 2977, 2986, 1728, 1677, 1486, 1445, 1396, 1369, 1309, 1228, 1155, 916, 716; 1H NMR (CDCl3) δ 10.0-9.7 (1H, brm), 7.86 (2H, d, J=7.5), 7.62-7.38 (3H, m), 7.3-5.6 (2H, brm), 4.57 (1H, brd, J=4.0), 4.05-3.77 (2H, m), 3.00-2.82 (1H, m), 2.80-2.43 (3H, m), 2.20-2.03 (1H, m), 2.00-1.47 (1H, m), 1.62-1.14 (11H, m); 13C NMR (CDCl3) δ 175.00, 171.17, 167.62, 160.68, 132.39, 131.77, 128.67, 127.38, 82.27, 54.38, 48.04, 46.35, 33.62, 28.02, 25.68, 21.61.
