Abstract:
Disclosed are processes for producing benzopyran compounds, reduced 2-(chroman-2-yl) acetic acid compounds and 2-(6-aminochroman-2-yl)acetic acid esters which are intermediates for producing platelet aggregation inhibitors and/or are themselves potent platelet aggregation inhibitors.
Abstract:
The present invention relates to a process of manufacture of compounds of formula (B) wherein R 1 , R 2 and R 3 are as defined for compounds of formula (A), which process comprises hydrogenation of compounds of general formula (A). In particular, the present invention relates to an improved process for the manufacture of Lacosamide (LCM), (R)-2-acetamido-N-benzyl-3-methoxypropion-amide (B1), which is useful as an anticonvulsive drug.
Abstract:
Disclosed are processes for coupling amino substituted 2-chromanyl derivatives and benzoyl derivatives via an amide bond, and intermediates for producing platelet aggregation inhibitors and for producing potent platelet aggregation inhibitors. Also disclosed are processes for producing such compounds from chiral intermediates to provide desired enantiomers, and methods for using the compounds as platelet aggregation inhibitors.
Abstract:
The present patent application relates to an alternative process for the preparation of amino derivatives. In particular, the present application relates to an improved process for the manufacture of Lacosamide (LCM) , (R)-2-acetamido-N-benzyl-3-methoxypropion-amide, which is useful as an anticonvulsive drug. In a particular aspect, the present invention relates to a process of manufacture of optically enriched (R)-2-acetamido-N-benzyl-3-methoxypropion-amide (I) comprising resolution of 2-acetamido-N-benzyl-3-methoxypropion-amide (II).
Abstract:
The present invention relates to intermediate compounds useful for the preparation of 1,2,5-thiadiazole compounds, including unsymmetrically substituted compounds such as 4-(3-secondary amino-2-hydroxy-propoxy)-1,2,5-thiadiazole compounds and azacyclic or azabicyclic 1,2,5-thiadiazole compounds and to processes for making the same.

Abstract:
The present invention is directed to a method of carrying out Suzuki- Miyaura CC-coupling reactions, comprising reacting an aryl halide with an aryl boronic acid in an organic solvent in the presence of an oxide supported palladium catalyst and a base, characterized in that the base is added in the form of an aqueous solution with a constant flow rate within a predetermined period of time at the beginning of the reaction.
Abstract:
The present invention provides a process for the preparation of lacosamide in substantially optically pure form, which in one aspect comprises the following steps: (i) resolution of O -methyl-D,L-serine to provide O -methyl-D-serine in substantially optically pure form; (ii) acetylation of O -methyl-D-serine thereby obtained to provide the N -acetyl 10 derivative thereof in substantially optically pure form; (iii) activating the carboxy group of the compound thereby obtained; and (iv) reacting the compound thereby obtained with benzylamine.
