Procedure

Following the procedure described in Example 27, but starting from ethyl 4-(2,3-epoxypropoxy)indole-2-carboxylate (25.1 g), obtained from ethyl 4-hydroxyindole-2-carboxylate and epichlorohydrin according to the method of Belgian Patent 739,545, and 2-aminotetralin (14.8 g) in ethanol (120 ml), N-(1,2,3,4-tetrahydronaphth-2-yl)-2-hydroxy-3-(2-ethoxycarbonylindol-4-yloxy)propanamine hydrochloride is obtained ((i): R=H, Ar=radical 15 wherein Z is ethoxy, and the chain is attached to position 2 of the tetralin moiety) which is crystallized from a mixture ethanol/isopropanol 2/1.
