he problem is to provide a pharmaceutical for the prevention or treatment of hyperphosphatemia. The solution is a salt of a compound including formula (I), or a crystal of a hydrate thereof.
disodium 4- [2- (4 – {[2 – ({3 – [(trans-4-carboxy-cyclohexyl) (ethyl) sulfur carbamoyl] benzoyl} amino) -5- (piperidin-1-yl ) benzoyl] amino} phenyl) ethyl] benzoic acid trihydrate
Disodium 4- [2- (4 – { [2 – ({3 – [(trans-4-carboxylatocyclohexyl) (ethyl) sulfamoyl] benzoyl} amino) – 5- (piperidin-1-yl) benzoyl] amino} phenyl) ethyl] benzoate trihydrate
of α crystal
4- [2- (4 – {[2 – ({3 – [(trans-4-carboxy-cyclohexyl) (ethyl) sulfur carbamoyl] benzoyl} amino) -5- (piperidin-1-yl) benzoyl] amino} phenyl) ethyl] 1 mol / L NaOH aqueous solution to benzoic acid (1.2 g) (3.1 mL) was added and dissolved completely. After stirring at room temperature for 1 day was added acetonitrile (60 mL), at 40 ° C.
and stirred for further 1 day. The precipitated solid was collected by filtration, and 3 hours drying under reduced pressure at room temperature to give the title compound 1.1 g (85%).
in water (46.4 mL), 1-PrOH (72 mL), 4 mol / L NaOH aqueous solution (25.54 mL) was added, then filtered after stirring insolubles at room temperature, water / 1-PrOH: was washed with (3 7, 80 mL). The filtrate was heated up to 40 ℃, 1-PrOH the (160 mL) was added, and further seed crystal (α crystals, 0.2g) was added. Then the temperature was raised to 50 ℃, 1-PrOH (96 ml) was added, and the mixture was stirred overnight.Thereafter, 1-PrOH (480 ml) was added and after overnight stirring, was collected by filtration the precipitated solid was cooled to room temperature.Thereafter, and vacuum dried overnight at 40 ° C., to give the title compound 39.4 g (96%).
