実験手順

To a solution of 4-((S)-2-(4-ethylthiazol-2-yl)-2-((S)-2-(methoxycarbonylamino)-3-phenylpropanamido)ethyl)-phenylsulfamic acid (75) (150 g, 0.272 mmol) in methanol (1.2 L) was added 50% NaOH (11.3 g, 0.272 mol, 1.0 equiv.) at room temperature. The resulting mixture was stirred at rt for 30 min and then concentrated under reduced pressure to give the crude product, which contained a small amount of Me3N and MeOSO3Na. To a stirred slurry of the crude product (75 g) in H2O (150 mL) was added aq. NaOH (2 g, 0.05 mol; in 50 mL H2O) in dropwise at room temperature. The slurry was continued to stir for 20 min, filtered and washed with water (10 mL) and ethyl ether (50 mL). Then the filter cake was dried under reduced pressure at 50° C. to give 62 g (83%) of the desired compound. LC/MS (M−1): 531; H-NMR (300 MHz, CD3OD) δ: 7.21-6.98 (m, 10H), 5.40-5.36 (t, 1H, J=6.9 Hz), 4.38-4.34 (t, 1H, J=7.5 Hz), 3.61 (s, 3H), 3.24-3.23 (m, 1H), 3.11-3.01 (m, 2H), 2.81-2.74 (m, 3H), 1.31-1.26 (t, 3H, J=7.5 Hz); HPLC: 98.5%.
