Versuchsvorschrift

A suspension comprising 422 mg (0.80 mmol) of N-[2-t-butyl-5-(4-cyclohexyl-3-hydroxybutyl)phenyl]-2-(9H-xanthen-9-yl)acetamide (prepared as described in Example 12), 311 mg (1.51 mmol) of dicyclohexylcarbodiimide, 142 μl (1.76 mmol) of pyridine, 20 mg (0.16 mmol) of 4-(N,N-dimethylamino)pyridine and 156 mg (0.96 mmol) of 2-(1-imidazolyl)acetic acid hydrochloride in 10 ml of methylene chloride was stirred for 3 days. At the end of this time, insoluble materials were filtered off, and the filtrate was washed with water and with a saturated aqueous solution of sodium chloride, in that order, after which it was dried over anhydrous sodium sulfate. The solvent was then removed by distillation under reduced pressure. The resulting residue was purified by column chromatography through 75 g of silica gel, using a 1:4 by volume mixture of ethyl acetate and hexane as the eluent, to give 507 mg (a quantitative yield) of the title compound as a colorless foam-like material.
