実験手順

N-(2-Hydroxyethyl)benzamide (200 parts by weight) and stannous octoate (1 part by weight) were charged to the standard reaction vessel as one lot. The mixture was heated to 230° C. at 250 mm Hg (33 kPa) and maintained at these conditions for 4 hours by when water had ceased to distil over. The residues were distilled under vacuum to give 2-phenyl-2-oxazoline (yield 58%), b.p. 115° C./1 mm Hg (0.13 kPa).
