    摘要: The invention relates to a process for the synthesis of 1H-imidazo[4,5-c] quinoline 4-cyano and 1H-imidazo[4,5-c] quinoline 4- carboxamide intermediates useful in preparing 1H-imidazo[4,5-C] quinoline 4-amines, a process for preparing 1H-imidazo [4,5-C] quinoline 4-amines using such intermediates; and, to the 1H-imidazo[4,5-c] quinoline 4-cyano and 1H-imidazo[4,5-c] quinoline 4- carboxamide intermediates. More particularly, the invention relates to a process for the preparation of 1-isobutyl-1H-imidazo [4,5-C] quinoline 4-amine (Imiquimod) using two intermediates, 1-isobutyl-1H-imidazo[4,5-c]quinoline 4-cyano and 1-isobutyl-1H-imidazo[4,5-c]quinoline 4-carboxamide, and to the said intermediates.

    摘要: New polymorphic forms of pravastatin sodium are provided. Each of the new forms is selectively obtained by crystallization from different solvent systems, each solvent system having a protic component, and by controlling the rate of crystallization through temperature. The new polymorphic forms are suitable for use as active substances of pharmaceutical dosage forms for reduction of serum cholesterol levels in the bloodstream.
