YieldReaction ConditionsOperation in experiment
98% for 4 h; Heating / reflux A solution of N-(6-iodobenzo[d][1,3]dioxol-5-yl)acetamide (200 mg, 0.656 mmol) and NaOH (1.31 g, 32.8 mmol) in ethanol (26 mL) and water (6 mL) was heated to reflux with stirring for 4 h.
The mixture was cooled and the solvent was removed under vacuum.
The residue was partitioned between methylene chloride (100 mL) and water (100 mL).
The organic layer was washed with water (2*100 mL), dried (MgSO4) and evaporated under vacuum to give 6-iodobenzo[d][1,3]dioxol-5-amine (170 mg, 98percent) as orange solid. LCMS: 264 [M+1]+; 1H NMR (DMSO-d6) δ 4.88 (s, 2H), 5.87 (s, 2H), 6.47 (s, 1H), 7.07 (s, 1H).
98% With sodium hydroxide In ethanol; water A solution of N-(6-iodobenzo[d][1,3]dioxol-5-yl)acetamide (200 mg, 0.656 mmol) and NaOH (1.31 g, 32.8 mmol) in ethanol (26 mL) and water (6 mL) was heated to reflux with stirring for 4 h.
The mixture was cooled and the solvent was removed under vacuum.
The residue was partitioned between methylene chloride (100 mL) and water (100 mL).
The organic layer was washed with water (2*100 mL), dried (MgSO4) and evaporated under vacuum to give 6-iodobenzo[d][1,3]dioxol-5-amine (170 mg, 98percent) as orange solid. LCMS: 264 [M+1]+; 1H NMR (DMSO-d6) δ 4.88 (s, 2H), 5.87 (s, 2H), 6.47 (s, 1H), 7.07 (s, 1H).
98% With sodium hydroxide In ethanol; water for 4 h; Reflux A solution of N-(6-iodobenzo[d][1,3]dioxol-5-yl)acetamide (200 mg, 0.656 mmol) and NaOH (1.31 g, 32.8 mmol) in ethanol (26 mL) and water (6 mL) was heated to reflux with stirring for 4 h. The mixture was cooled and the solvent was removed under vacuum. The residue was partitioned between methylene chloride (100 mL) and water (100 mL). The organic layer was washed with water (2×100 mL), dried (MgSO4) and evaporated under vacuum to give 6-iodobenzo[d][1,3]dioxol-5-amine (170 mg, 98percent) as orange solid. LCMS: 264 [M+1]+; 1H NMR (DMSO-d6) δ 4.88 (s, 2H), 5.87 (s, 2H), 6.47 (s, 1H), 7.07 (s, 1H)
83% With sodium hydroxide; water In ethanol at 90℃; for 16 h; To a stirred solution of Intermediate 57 (5.0 g, 16.4 mmol) in EtOH (150 mL) was added a solution of sodium hydroxide (20.0 g, 500 mmol) in water (120 mL). The reaction mixture was stirred at 900C for 16 h, then cooled to r.t. and extracted with DCM (4 x 200 mL). The combined organic fractions were washed with brine (100 mL), dried (Na2SO4), filtered and concentrated in vacuo to give the title compound (3.5 g, 83percent) as a white solid. δH (CDCl3) 7.08 (IH, s), 6.40 (IH, s), 5.90 (2H, s), 3.80 (2H, br. s).
