Reaction Steps

8-Methoxy-N-propyl-2-aminotetralin (Arvidsson L.-E. et al., J. Med. Chem., 27, 45 (1984) (2 g, 10 mmol), N-(3-iodopropyl)-2,3-dihydro-1,1-dioxo-3-benzisothiazolone (7.5 g), sodium carbonate (2.5 g), and acetonitrile (25 ml) were heated to reflux for 24 hours. After cooling, the solvent was removed in vacuo and the residue placed on a flash silica gel column (3 cm×35 cm) and eluted with ethyl acetate/hexane (5:95, 10:90, 15:85, 20:80, successively). Solvent removal in vacuo afforded the title compound as a white powder (m.p. 131° C.).
