Summary for Patent: 5,629,425

Title:	Haloalkyl hemisolvates of 6-hydroxy-2-(4-hydroxyphenyl)-3-[4-piperidinoethoxy)-benzoyl]benzo[b]thiophene
Abstract:	The present invention is directed to chemical processes for preparing 2-aryl-6-hydroxy-3-[4-(2-aminoethoxy)benzoyl]benzo[b]thiophenes. The present invention is also directed to crystalline solvates and a non-solvated crystalline form of 6-hydroxy-2-(4-hydroxyphenyl)-3-[4-(2-piperidinoethoxy)benzoyl]benzo[b]thiophene hydrochloride, as well as processes for their preparation.
Inventor(s):	Elizabeth S. LaBell, John M. McGill, Randal S. Miller
Assignee:	Eli Lilly and Co
Application Number:	US08/308,325
