摘要:
The present invention provides novel crystalline polymorph forms of atomoxetine hydrochloride denominated Forms B and C and methods for their preparation, as well as methods for the preparation of Form A. The present invention provides pharmaceutical compositions that comprise atomoxetine hydrochloride Form B, Form C, or mixtures thereof that can be used to treat attention deficit/hyperactivity disorder.
摘要:
The present invention provides improved processes for the preparation of atomoxetine hydrochloride under reaction conditions that improve reaction yields and facilitate commercial synthesis. In particular, the invention is directed to the synthesis of atomoxetine HCl by adding HCl to a mixture of (R)-(−)-tomoxetine (S)-(+)-mandelate with an organic solvent, with or without a base and water. In preferred embodiments, the atomoxetine hydrochloride produced is Form A.
