Procedure
The title compound is prepared from (4-benzyl-piperidin-1-yl)-oxo-acetic acid (Example 5b) and 5-amino-1,3-dihydro-2,1-benzisothiazole-2,2-dioxide [J. Het. Chem., 23, 1645. (1986)] according to the method described in Example 2. The filtered crystals are purified by column chromatography using Kieselgel 60 (Merck) as adsorbent and toluene:methanol=4:1 as eluent. Melting Point: 181-182° C. (isopropanol)
