    摘要: The present invention provides an improved method of chromatographically separating the isomers of (1R,rR)-atracurium salts by high-performance liquid chromatography (HPLC), in the absence of a strong acid. The separation is preferably performed on a silica gel HPLC column using an eluent containing an organic solvent, a polar aprotic co-solvent and a weak organic acid.

    摘要: The present invention provides a process for preparing highly pure 4-amino-1-isobutyl-1H-imidazo[4,5-c]quinoline (imiquimod). The process preferably includes heating 4-chloro-1-isobutyl-1H-imidazo[4,5-c]quinoline of formula (II) with ammonia in a polar aprotic solvent at relatively moderate pressure to produce imiquimod, and optionally purifying the imiquimod. The process of the present invention can produce highly pure imiquimod in high yield.
