Procedure
A solution of 3-(2-aminophenylthiomethyl)1,2,4-oxadiazole (4.2 g) in 3,4-dimethoxybenzaldehyde diethyl acetal (9.6 g) was heated under reflux for 30 minutes. On cooling and the addition of hexane yellow crystals precipitated. These were removed by filtration and re-crystallised from ethanol to give 3-[2-(3,4-dimethoxybenzylideneamino)phenylthiomethyl]-1,2,4-oxadiazole, m.p. 146°.
