実験手順
152.5 Grams (1 mole) of chloroacetaldehyde-diethylacetal were heated at 100° C for 6 hours on the steam bath, together with 162 g (1 mole) of 4-methylthiophenol-sodium salt in 200 ml of dimethylacetamide (in a manner analogous to Comptes Rendus 194, 617 (1932)). After the precipitated sodium chloride had been suction-filtered, the solvent was removed by distillation under reduced pressure. 4-Methylthio-phenoxyacetaldehyde-diethylacetal was obtained as an oily residue which was directly further reacted.
