Demonstration on Pilot-Plant Scale of the Utility of 1,5,7-Triazabicyclo[4.4.0]dec-5-ene (TBD) as a Catalyst in the Efficient Amidation of an Unactivated Methyl Ester

摘要

The utility of 1,5,7-triazabicyclo[4.4.0]dec-5-ene as a reagent to facilitate efficient amide formation by reaction of an amine with an unactivated ester was demonstrated on pilot-plant scale as a key step in the synthesis of an H-PGDS inhibitor.
