Procedure
0.6 g of the compound obtained in Example 17c and 0.34 g of 2-chloro-benzothiazole were refluxed for 23 hours in 15 ml of isopropanol. The reaction mixture was cooled to room temperature, and the solvent was evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate:hexane) to obtain 0.32 g of the title compound (yield: 43%).
