This application relates to a compound of formula I (or a pharmaceutically acceptable salt of the compound) as defined herein, pharmaceutical compositions thereof, and its use as an inhibitor of factor Xa and/or thrombin, as well as a process for its preparation and intermediates therefor.
The transamidation between formamide and various amines proceeds under heating, without any catalyst nor solvent, providing thus green and neutral conditions for the formylation of primary and secondary amines. The resulting amide product can be directly transformed, in a one pot sequence, into monomethylamine. (C) 2013 Elsevier Ltd. All rights reserved.
