Abstract: The invention relates to an improved process for preparing [(1R), 2S]-2-aminopropionic acid 2-[4-(4-fluoro-2-methyl-1H-indol-5-yloxy)-5-methylpyrrolo[2,1-f][1,2,4]triazin-6-yloxy]-1-methylethyl ester of the formula: Compound I has been shown to be useful for the treatment of certain types of cancer.

Abstract: The present invention provides a solventless process for the catalytic hydrogenation of esters of 4,4,4-trihaloacetoacetic acid using a platinum catalyst in the presence of an acid or base co-catalyst to provide the analagous 3-hydroxybutyrate ester. Such 3-hydroxybutyrate esters are useful as solvents, cleaners or fine chemical intermediates.

Abstract: The present invention provides a process for preparing esters or thioesters of trifluoroacetic acid from trifluoroacetyl chloride and an alcohol or a thiol with the ester or thioester being present as the solvent. Esters and thioesters of trifluoroacetic acid are fine chemical intermediates which can be used in the manufacture of pharmaceuticals, agricultural chemicals, liquid crystals, dyes and industrial chemicals. Trifluoroacetate esters and thioesters can also be used as solvents in the manufacture of other fine chemicals, pharmaceuticals, agricultural chemicals, liquid crystals, industrial chemicals and dyes.

Abstract: A nucleophilic substitution reaction on optionally substituted dihalobenzenes is carried out in the presence of an optional catalyst followed by formation of and subsequent carboxylation of a Grignard reaction intermediate. In particular the present invention provides a process leading to optionally substituted hydroxybenzoic, alkanoyloxybenzoic, formyloxybenzoic and alkoxybenzoic acids from 1-substituted 2,6-dihalobenzenes. The invention also provides a process for the direct formation of an acyl chloride from a Grignard reagent by quenching with phosgene.
