A mixture of 0.10 g 4-methoxy-7-morpholin-4-yl-benzothiazole-2-carboxylic acid (2-oxo-cyclohexyl)-amide and 0.34 g ammonium triflouroacetate was melted at 165° C. for 50 minutes and, after cooling to room temperature, suspended in water. Extraction with dichloromethane and chromatography on silicagel with ethylacetate/hexane 6:4 gave 0.04 g (39%) 4-methoxy-7-morpholin-4-yl-2-(4,5,6,7-tetrahydro-1H-benzoimidazol-2-yl)-benzothiazole as light brown solid; MS (ISP): m/e=371 (M+H+).
