preparation example Construction

[0049] The preparation of crystalline Form I' is generally carried out in a suitable inert diluent, examples of which include, but are not limited to, acetone, acetonitrile, ethyl acetate, methyl ethyl ketone, methanol, ethanol, isopropanol, isobutanol, Dichloromethane, methyl t-butyl ether, cyclopentyl methyl ether, hexane, etc., and mixtures thereof, optionally containing water. Mixtures of inert diluents (also known as solvent systems) include acetone and water, acetonitrile and water, ethanol and ethyl acetate, ethyl acetate and hexane, and lower alcohols (C 1-6 Alkyl-OH) and water, such as methanol and water and isopropanol and water. A particularly suitable solvent system includes ethyl acetate and water. After crystallization is complete, the crystalline compound can be separated from the reaction mixture by any conventional method, such as precipitation, filtration, concentration, centrifugation, drying in vacuo, and the like.

[0050] In one embodiment, crystalline ...

example A

[0208] Freezing solutions suitable for the preparation of injectable solutions are prepared as follows:

[0209]

[0210] Representative procedure: Dissolve excipients (if present) in about 80% water for injection, add active compound I or I' and dissolve. The pH was adjusted to 3 to 4.5 with 1M sodium hydroxide, and then the volume was adjusted to 95% of the final volume with water for injection. Check pH and adjust if necessary, and adjust volume to final volume with water for injection. The formulation is then sterile filtered through a 0.22 micron filter and placed into sterile vials under aseptic conditions. Vials were capped, labeled and stored frozen.

example B

[0212] Lyophilized powders or crystalline solids suitable for the preparation of injectable solutions are prepared as follows:

[0213]

[0214] Representative procedure: Dissolve excipients and / or buffers (if present) in about 60% water for injection. Add active compound I or I', dissolve, adjust pH to 3 to 4.5 with 1M sodium hydroxide and adjust volume to 95% of final volume with water for injection. Check pH and adjust if necessary, and adjust volume to final volume with water for injection. The formulation is then sterile filtered through a 0.22 micron filter and placed into sterile vials under aseptic conditions. The formulation is then lyophilized using an appropriate lyophilization cycle. Will be capped (optionally under partial vacuum or dry nitrogen), labeled and stored frozen.
