Participants

Reaction Steps

1.9 g (6.0 mmol) of 2-(4-bromobutyl)-1,2-benzisothiazol-3(2H)-one 1,1-dioxide were added dropwise to the solution of the 1.3 g (6.0 mmol) of 8-methoxy-2-propylamino-1,2,3,4-tetrahydronaphthalene and 1.3 g (12 mmol) of triethylamine in 15 ml of dimethylformamide. After stirring for 15 hours at room temperature, a spatula tip of sodium iodide was added, and the mixture was heated to 60° C. After 4 hours at this temperature, 0.4 g of the above aminotetralin and 0.3 g of triethylamine were added. Chromatography on silica gel (toluene/ethyl acetate gradients) of the crude product, obtained after removal of the solvent in vacuo, yielded 0.70 g (25%) of the title compound as a yellowish oil.
