Versuchsvorschrift

1-Methyl-8-hydroxymethyl-1,2,3,4-tetrahydroquinoline (0.89 g) was dissolved in dichloromethane (30 ml), and thionyl chloride (1.09 ml) was added thereto, and the mixture was stirred for 2 hours at 45° C. After distilling off the solvent, n-hexane was added to the residue, and the solvent was distilled off under reduced pressure to give 1-methyl-8-chloromethyl-1,2,3,4-tetrahydroquinoline (1.1 g).
