Sodium Thiosulfate → HCID 23591426, compound

Participants

Reaction Steps

To a solution of N-(3,4-dimethoxyphenyl)acetamide (6.3 g, 32.0 mmol) in DCM (100 mL) and AcOH (6.5 mL) was added a solution of iodine monochloride (6.3 g, 39 mmol) in DCM (50 mL) dropwise. The reaction mixture was stirred at r.t. for 16 h. Aqueous sat. Na2S2O3 (500 mL) was added. The organic fraction was separated, washed with water (2×250 mL), then brine (100 mL), dried (Na2SO4), filtered and concentrated in vacuo. Purification by column chromatography (SiO2, 50% EtOAc/hexanes) gave the title compound (7.5 g, 72%) as a dark solid. LCMS (ES+) 321.8 (M+H)+, RT 2.67 minutes (Method 4).
