実験手順

A mixture of methyl 4-{1-[(4-{[(benzyloxy)amino]carbonyl}phenoxy)carbonyl] cyclohexyl)-benzoate (E23) (0.063 g, 0.129 mmol) and 5% palladium on activated carbon (0.026 g) in methanol (1 ml) was hydrogenated at room temperature for 50 minutes. The black suspension was filtered, the catalyst was washed with methanol (3×1 ml), and the filtrate was evaporated to give a viscous oil. The oil was converted to white crystals by stirring in diethyl ether (3 ml) overnight. The solid was filtered, washed with diethyl ether (0.5 ml), and dried in vacuum to give the title compound (0.033 g, 64%) as white crystals, m.p. 129-131° C. 1H NMR (DMSO-d6, HMDSO) δ: 1.13-1.99 (8H, m); 2.35-2.58 (2H, m, overlapped with a signal of DMSO); 3.86 (3H, s); 7.05 (2H, d, J=8.6 Hz); 7.65 (2H, d, J=8.4 Hz); 7.77 (2H, d, J=8.6 Hz); 8.01 (2H, d, J=8.4 Hz); 9.07 (1H, s); 11.25 (1H, s). HPLC analysis on Symmetry C8 column: impurities 2.5% (column size 3.9×150 mm; mobile phase acetonitrile−0.1M phosphate buffer (pH 2.5), 60:40; detector UV 254 nm; sample concentration 0.5 mg/ml; flow rate 1.0 ml/min). Anal. Calcd for C22H23NO6*0.35H2O, %: C, 65.45; H, 5.92; N, 3.47. Found, %: C, 65.17; H, 5.76; N, 3.49.
