Potassium Carbonate → HCID 19605757, compound

Participants

Reaction Steps

A solution of 140 mg of 2-formylamino-5-hydroxybenzamide in 15 ml of dry dimethylformamide is treated subsequently with 160 mg of potassium carbonate and 180 mg of 2,5-dimethoxybenzylbromide. The mixture is stirred at room temperature for 4 hours, and then the solvent is distilled off in vacuo. The residue is partitioned between water and ethyl acetate, and the separated organic layer is dried over magnesium sulfate and evaporated in vacuo. Purification of the crude product thus obtained by silica gel chromatography (ethyl acetate) gives the title compound as colourless crystals. mp: 135-138°.
