Procedimiento

In 20 ml of dimethylformamide was dissolved 0.26 g (0.8 mmol) of Compound (1), which is 4-(5,6-dimethoxybenzothiazolyl)benzoic acid. Further, 0.12 ml (0.9 mmol) of isobutyl chloroformate and 0.16 ml (0.9 mmol) of ethyl diisopropylamine were added thereto, followed by stirring at room temperature for 1 hour. Then, 0.10 g (0.9 mmol) of 6-aminohexanol was added thereto, followed by stirring for 1 hour and a half. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography to obtain 0.15 g of Compound (2).
