    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.

    摘要: Provided is a process for preparing gemcitabine or a salt thereof, which preferably includes selectively precipitating the β-anomer of a 3′,5′-di-O-protected-N4-trimethylsilyl-2′-deoxy-2′,2′-difluorocytidine, removing the protecting groups to produce gemcitabine, and, optionally, converting the gemcitabine into a salt. Preferably, the 3′ and 5′ protecting groups are the same or different, and at least one of the 3′ and 5′ protecting groups is cinnamoyl, naphthoyl, naphthylmethylcarbonyl, 2-methylbenzylcarbonyl, 4-methylbenzylcarbonyl or 9-fluorenylmethyloxycarbonyl. Also provided are methods for enriching the β-anomer from an anomeric mixture of a 3′,5′-di-O-protected-N4-trimethylsilyl-2′-deoxy-2′,2′-difluorocytidine, e.g., a N4-trimethylsilyl-2′-deoxy-2′,2′-difluoro-cytidine-3′,5′-diester, e.g., 3′,5′-dicinnamoyl-N4-trimethylsilyl-2′-deoxy-2′,2′-difluorocytidine, using a slurrying process, and methods for converting the β-anomer-enriched product into gemcitabine or a salt thereof.
