Reaction Conditions:
with triethylamine in dichloromethane;
Steps:
General procedure C: preparation of N-alkyl-3-oxobenzo[d]isothiazole-2(3H)-carboxamide analogues 6a-w
General procedure: To a solution of triphosgene (2.96 g, 10 mmol) in DCM (20 ml) was added dropwise to primary amine 4 (10 mmol) in DCM (20 ml) followed by the dropwise addition of triethylamine (3 ml) in DCM (10 ml). The solvent was removed on a rotary evaporator. The resulting residue was dissolved in DCM (20 ml), and 1,2-benzisothiazol-3-one (1.51 g, 10 mmol) in THF (20 ml) was added. After the mixture was refluxed for 30 min, the solvent was removed on a rotary evaporator. The residue was dissolved in acetone (30 ml) and mixed with water (30 ml). The precipitate was collected on a funnel by vacuum filtration and washed with water-acetone (1:1,4 × 5 ml) to afford the final compound.
