Procedure

A suspension of 249 mg (0.474 mmol) of (R)-N-[2-t-butyl- 5-(4-cyclohexyl-3-hydroxybutyl)phenyl]-2-(9H-xanthen-9-yl)acetamide (prepared as described in Example 100), 218 mg (1.05 mmol) of benzyl hydrogen succinate, 76 mg (0.62 mmol) of 4-(N,N-dimethylamino)pyridine and 256 mg (1.34 mmol) of 1-ethyl-3-(3'-dimethylaminopropyl)carbodiimide hydrochloride in 5 ml of tetrahydrofuran was stirred for 17 hours at room temperature. At the end of this time, the reaction mixture was diluted with ethyl acetate, and the diluted mixture was washed with 2N aqueous hydrochloric acid, with water, with a saturated aqueous solution of sodium hydrogencarbonate and with a saturated aqueous solution of sodium chloride, in that order. The organic phase was then dried over anhydrous magnesium sulfate, and the solvent was removed by distillation under reduced pressure. The resulting residue was purified by column chromatography through 20 g of silica gel, using a 1:9 by volume mixture of ethyl acetate and hexane as the eluent, to give 352 mg (a quantitative yield) of the title compound as a glassy material.
