Method For Solution Phase Detritylation Of Oligomeric Compounds

View page
US Patent:
20160244477, Aug 25, 2016
Filed:
Oct 21, 2014
Appl. No.:
15/027505
Inventors:
- Carlsbad CA, US
Dana Chreng - San Marcos CA, US
Assignee:
Ionis Pharmaceuticals, Inc. - Carlsbad CA
International Classification:
C07H 21/04
C07H 1/00
Abstract:
Provided herein are methods for the synthesis of oligomeric compounds wherein removal of the 5′-terminal trityl group is performed at reduced temperature and lower pH relative to standard methods. In certain embodiments, the present methods provide detritylated oligomeric compounds having a reduced percentage of depurination relative to the same detritylated oligomeric compounds prepared using standard methods. In certain embodiments, the present methods provide detritylated oligomeric compounds with increased purity relative to the same detritylated oligomeric compounds prepared using standard methods. In certain embodiments, the present method provide an increased rate of detritylation compared to standard methods.
