4-((6bR,10aS)-3-methyl-2,3,6b,9,10,10a-hexahydro-1H-pyrido[3',4':4,5]pyrro- lo[1,2,3-de]quinoxalin-8(7H)-yl)-1-(4-fluorophenyl)-1-butanone toluenesulfonic acid salt crystal forms

Abstract:

The present invention relates to toluenesulfonic acid addition salt crystals of 4-((6bR,10aS)-3-methyl-2,3,6b,9,10,10a-hexahydro-1H-pyrido[3',4': 4,5]pyrrolo[1,2,3 -de]quinoxalin-8(7H)-yl)-1-(4-fluorophenyl)-1-butanone, and methods of using such crystals as 5-hydroxytryptamine 2 receptor agonists and antagonists in treating disorders of the central nervous system.
