3-[4-(4-Fluorophenyl)Piperazin-1-ylmethyl]-5-Methyl-1,3-Benzoxazol-2(3H)-One and 3-[4-(2-Fluorophenyl)Piperazin-1-ylmethyl]-5-Methyl-1,3-Benzoxazol-2(3H)-One

Abstract

The planar benzoxazolinone ring systems of C<inf>19</inf>H <inf>20</inf>FN<inf>3</inf>O<inf>2</inf> were analyzed. The piperazine ring consisted chair conformation and benzoxazolinone ring system was found to be present in perpendicular direction to it. The structures contained intermolecular C-H...O contacts and interactions between benzoxazolinone and fluorophenylpipeprazine were segregated. The investigations for stereochemistry of molecules and assigned structures were performed using X-ray analysis.
