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 title compounds, both C₁₉H₂₀FN₃O₂, contain essentially planar benzoxazolinone ring systems, within which the C-N bond distances and angles do not differ significantly between the two compounds. In both cases, the piperazine ring adopts an almost perfect chair conformation and the benzoxazolinone ring system lies nearly perpendicular to it. The structures contain intermolecular C-HO contacts, and the interactions between the benzoxazolinone and fluorophenylpiperazine portions of the molecules are segregated.

Formula: C₁₉H₂₀FN₃O₂ and C₁₉H₂₀FN₃O₂
