Reaction Steps
A solution of sodium hydroxide (0.018 g, 0.47 mmol) in water (0.2 mL) was added to a solution of Example 2 (0.167 g, 0.47 mmol) in methanol (5 mL) and stirred at 25° C. for 15 min. The solvent was removed under vacuum, and dried to obtain the title compound. Yield: 0.16 g, (91%); 1H NMR (DMSO-d6, 300 MHz): δ 2.55 (s, 3H, CH3), 4.92 (s, 2H, CH2), 5.57 (s, 2H, NH2), 6.60 (m, 2H, Ar), 7.90 (s, 1H, Ar), 8.10 (s, 1H, Ar); MS: m/e (ES−) 352 (M-Na); analysis: C15H11ClNNaO5S.2H2O requires C, 43.75,H, 3.67, N, 3.40, Cl, 8.61, S, 7.79; found: C, 44.20,H, 3.34, N, 3.49, Cl, 9.25, S, 8.36%.
