反应详情

51.2 μl (0.39 mmol; 3 equivalents) of 4-(2-aminoethyl)morpholine is added to 27 mg (0.129 mmol) of 5-methoxy-2-methyl-4,7-dioxobenzothiazole in solution in 2 ml of anhydrous ethanol. The reaction mixture is stirred under reflux for 18 hours then the solvent is evaporated off under reduced pressure. The residue is purified on a silica column (eluent: 5% methanol in dichloromethane). The expected compound is obtained in the form of a red powder.
