A short, efficient 2-step synthesis of desethylchloroquine is achieved by generating an internal amide ion from the secondary nitrogen in chloroquine, followed by in situ reaction with 2,2,2-trichloroethyl chloroformate giving rapid elimination of ethylene. The carbamate thus produced easily undergoes deprotection to the target compound at room temperature.
Small fiber neuropathy is treated or prevented by topically administering to a subject in need thereof topically active quinoline compounds or pharmaceutically acceptable salts thereof under conditions effective to treat or prevent neuropathy in the subject. Glial cell-derived neurotrophic factor (GDNF) receptors are modulated with the subject active quinoline compounds, which may be formulated in topical lotions.
