Versuchsvorschrift

N-Hydroxymethylisatin (10 g, 0.056 mol) was added to thionyl chloride (100 ml) and the mixture was heated under reflux for 2 hours. N-Chloromethylisatin (about 11 g) was obtained by distilling the remaining thionyl chloride under reduced pressure. The melting point was 121° to 123° C.
