Crystal structure of methyl (6-(2-fluorobenzoyl)-5-chloro- 2-benzoxazolinon-3-yl)-acetate, C17H11ClFNO5

Abstract

C 17 H 11 ClFNO 5 ,monoclinic, P 12 1 / c 1(no. 14), a =7.489(5) Å, b =18.367(5) Å, c =11.752(5) Å, Source of materialThe mixture of potassiumc arbonate (5.75 mmol), methyl chloroacetate (5.75 mmol), the acetic acid and propanoic acid derivatives of 6-(2-fluorobenzoyl)-5-chloro-2-benzoxazolinone (5 mmol; 1:1, v / v )i n3 0m La cetone were heated to reflux and stirredfor 4h.100 gIce water wasadded to the cooled (273-283 K) reaction mixture. After stirring for 1h ,t he precipitate wasc ollected by filtration, washed with water, dried, and recrystallized from ethanol(yield 81 %, m.p. 383-385 K). IR dataare available in the CIF. Discussion
