Embodiment 1

[0129] Bis-2-oxo-L-gulonic acid salt of compound of crystalline formula (Is)

[0130] 3-(3-Amino-2-(R)-hydroxy-propyl)-1-(4-fluoro-phenyl)-8-(8-methyl-naphthalen-1-ylmethyl)-1, 3,8-Triaza-spiro[4.5]decane-4-one (30g) was heated to dissolve in IPA (100mL), and the resulting mixture was maintained at 70-80°C with 2-oxo-L- A warm solution of gluconic acid (68.7 g, 0.235 mol) in IPA (250 g) was treated. The reaction mixture was maintained at this temperature for about 15-30 min, then cooled to 25 °C over about 1-2 h. The resulting solid was collected by vacuum filtration, washed with IPA (70 g) and dried in a vacuum oven at 60°C to afford the title compound as a solid.

Embodiment 2

[0132] Directly from the bis-2-oxo-L-gulonic acid salt of the compound of formula (Is) to prepare the mono Sulfate

[0133] Will contain 3-(3-amino-2-(R)-hydroxyl-propyl)-1-(4-fluoro-phenyl)-8-(8-methyl-naphthalen-1-ylmethyl)-1 , 3,8-Triaza-spiro[4.5]decane-4-one, bis-2-oxo-L-gulonic acid salt (10 g, 10 mmol) and sulfuric acid (1.1 g, 11 mmol) were heated in water to about 75-80°C and then treat the resulting solution with ethanol (60 g). A precipitate formed when cooled to 50°C. The reaction mixture was cooled to 20-25 °C over about 1.5-2 h, then stirred for about 10-12 h. The solid was filtered, washed with ethanol (30 g) and dried in a vacuum oven at 60°C to give the title compound as a solid.

Embodiment 3

[0135] Recrystallization of the monosulfate salt of the compound of formula (Is)

[0136] Will contain 3-(3-amino-2-(R)-hydroxyl-propyl)-1-(4-fluoro-phenyl)-8-(8-methyl-naphthalen-1-ylmethyl)-1 , 3,8-Triaza-spiro[4.5]decane-4-one, bis-2-oxo-L-gulonic acid salt (3.3 g, 5.74 mmol) in water (95 mL) was heated to 100 °C . The resulting solution was filtered hot and the filtrate was concentrated under reduced pressure and temperature (50 mbar, 60° C.) to remove approximately 80 g of water. While maintaining the reaction temperature between 60-70 °C, ethanol (34 mL) was added. After precipitation started, over a period of about 1.5-2 h, the reaction was cooled to 25 °C and stirring was continued for about 12-14 h. The solid was isolated by vacuum filtration, washed with water (2 x 7 mL) and ethanol (9 mL). The solid was dried in a vacuum oven at 60°C to give the title compound as a solid.
