Reaction Steps

To a stirred solution of 0.3 g (1.8 mmol) of 6-amino-3H-benzoxazole-2-thione [J. Org. Chem., 19; 758. (1954)] and 0.6 ml (4.3 mmol) of triethylamine in 20 ml of chloroform 0.5 g (1.8 mmol) of (4-benzyl-piperidine-1-yl)-oxo-acetyl chloride (Example 38c) in 10 ml of chloroform is added dropwise at 0° C. The reaction mixture is stirred at room temperature for 1 hour, then washed with water and the organic layer is concentrated. The residue is purified by column chromatography using Kieselgel 60 (Merck) as adsorbent and toluene:methanol=4:1 as eluent to yield 0.46 g (61.9%) of the title compound. Melting Point: 203° C. (isopropanol)
