Process For Preparing Substituted Anisidines

View page

US Patent:

7884246, Feb 8, 2011

Filed:

Nov 1, 2006

Appl. No.:

12/092454

Inventors:

Fabrice Gallou - Basel, CH
Heewon Lee - Parsippany NJ, US
Chris Hugh Senanayake - Brookfield CT, US
Jinhua J. Song - Hopewell Junction NY, US
Zhulin Tan - Danbury CT, US
Jinghua Xu - Danbury CT, US
Nathan K. Yee - Danbury CT, US

Assignee:

Boehringer Ingelheim International GmbH - Ingelheim am Rhein

International Classification:

C07C 259/00

US Classification:

564267, 564253, 564248

Abstract:

Disclosed is a process for preparing substituted anisidines of formula I starting from substituted cyclic hydroxy-ketones II via aromatization through a substituted oxime intermediate IV in which R is C-Calkyl or halogen, and Alk is C-Calkyl. The substituted anisidines of formula I have been found to be useful as intermediates in the preparation of agents for the treatment of hepatitis C viral (HCV) infections.
