Low temperature calorimetry of 3-fluoro-5-(3-pyridinyloxy) benzenamine and N-[3-fluoro-5-(3-pyridinyloxy)phenyl]-N’-3-pyridinyl urea
Abstract
The investigation on thermodynamic properties of drug
intermediates plays a crucial role in the design and synthesis of new drugs as
well as understanding their biological activities in vivo. In this work, the thermodynamic
properties of two drug intermediates of 3-fluoro-5-(3-pyridinyloxy) benzenamine
and N-[3-fluoro-5-(3-pyridinyloxy)phenyl]-N’-3-pyridinyl urea were studied by
means of low temperature calorimety performed in a Physical Property
Measurement System calorimeter. The heat capacities of these two compounds were
measured over the temperature region from (1.9 to 300) K, and the corresponding
thermodynamic functions were consequently calculated on the basis of the heat
capacity curve fitting. Additionally, a group
additivity method were employed for estimating the heat capacity values
of these two compounds at 298.15 K, which are in good agreement with the values
measured in this work.
