Abstract: The present invention provides, according to an aspect thereof, a novel process for the preparation of dronedarone [1] and pharmaceutically acceptable salts thereof. According to a preferred embodiment, the process comprises N-acetylating of p-anisidine or p-phenetidine with acetic anhydride, reacting of the obtained N-(4-alkoxyphenyl)acetamide with 2-bromohexanoyl chloride or bromide in the presence of aluminum chloride or bromide to obtain N-[3-(2-bromohexanoyl)-4-hydroxyphenyl]acetamide [6a], converting the compound [6a] into 2-butyl-5-benzofuranamine hydrochloride [12a] and subsequently converting [12a] into [1] or pharmaceutically acceptable salts thereof. In accordance with another aspect of this invention, there are provided novel intermediates, inter alia the novel compounds [6a] and [12a]. The novel intermediates of the present invention are stable, solid compounds, obtainable in high yields, which can be easily purified by crystallization and stored for long periods of time.

Abstract: The present invention provides a new and efficient process for the preparation of the dexmethylphenidate hydrochloride with high optical purity, the process comprising: (a) reacting a solution of threo-N-Boc-ritalinic acid with (S)-1-phenylethylamine, separating precipitated solid salt of (R,R)-enriched N-Boc-ritalinic acid with (S)-1-phenylethylamnine from the reaction mixture and recrystallizing, reslurring and/or trituring of said salt; (b) mixing the solid salt of (R,R)-N-Boc-ritalinic acid and (S)-1-phenylethylamine obtained in step (a) with aqueous acid and separating (R,R)-N-Boc-ritalinic acid from the mixture; and (c) reacting the (R,R)-N-Boc-ritalinic acid prepared in step (b) with hydrogen chloride and methanol to give dexmethylphenidate hydrochloride with optical purity of at least 99% ee. The present invention further provides salt of (R,R)-N-Boc-ritalinic acid with (S)-1-phenylethylamine as new intermediate in the preparation of dexmethylphenidate hydrochloride.

Abstract: The invention provides a novel process for the preparation of prostaglandins and analogues thereof, and new crystalline intermediates in the process.

Abstract: The present invention provides a new and effective process for the synthesis of 17-phenyl-18,19,20-trinor-PGF2? and its derivatives, including the anti-glaucoma drugs Bimatoprost and Latanoprost. The benefit of the present invention rises inter alia from the fact that a major intermediate involved in the synthesis of the above compounds may be isolated from a mixture containing also an undesired isomer, by crystallization. In addition, the undesired isomer may be oxidized to give the starting compound, which is then recycled.
