Dimethyl Sulfoxide → (3,7-Dichloroquinolin-8-yl)methyl nonanoate

Participants

Reaction Conditions

Reaction Steps

16 parts by weight of nonanecarboxylic acid, 20 parts by weight of 30% strength sodium methylate solution and 440 parts by weight of dimethylsulfoxide are stirred for 1 hour at 100° C. Thereafter, 24.5 parts by weight of 3,7-dichloro-8-chloromethylquinoline are introduced and the reaction mixture is stirred for a further 2 hours at 100° C. The reaction solution is then cooled, water is added and the precipitated solid is filtered off under suction and recrystallized from toluene. 32.5 parts by weight (89% of theory) of 3,7-dichloro-8-octylcarbonyloxymethylquinoline of melting point 92° C. are obtained.
