Abstract:
Disclosed are a preparation method of an orexin receptor antagonist compound 5-3, Crystalline forms I-IV of an orexin receptor antagonist compound 5-3 are provided. Also provided are processes of the preparing the orexin receptor antagonist compound 5-3 and its crystalline forms, as well as methods of using the crystalline forms I-IV for treating an orexin-related disease.

Claim (Index 16):
A process for preparing the crystal form of compound 5-3 of  claim 11 , which comprises:\n adding compound 5-3 into a polar organic solvent, heating to a temperature of 40\u00b0 C. to reflux temperature for dissolution, then slowly adding a weak polar or non-polar organic solvent dropwise, and after the addition is completed, cooling to a temperature of 0\u00b0 C. to 20\u00b0 C. in 1-10 hours, thereby forming the crystal; or adding compound 5-3 into a single organic solvent, a mixed organic solvent, a mixed solvent of a single organic solvent and water, or a mixed solvent of a mixed organic solvent and water, and conducting recrystallization or crystallization.
