A process for converting Laura Carb is isopropanolate and Laura Carb is isopropanol to loracabefin hydrate

摘要

The present invention relates to a crystalline isopropyl alcohol solvate of Laura Carb and is further characterized by a crystalline isomer of the compound of formula (I) below at a temperature of from about 50 DEG to about 90 DEG C. and a relative humidity of from about 60 to about 100% Propyl solvate forms of the compound of formula (I), and a process for the preparation of the crystalline monohydrate form of the compound of formula (I).
