20090275758 - Process for phenylacetic acid derivatives: e

20090270632 - Method for synthesizing benzotriazole: A method for synthesizing benzotriazole comprises acts of: preparing a first solvent comprising 2-(2-hydroxy-5-methylphenyl) benzotriazole, a basic agent and molecular sieves and a second solvent comprising 3-chloro-2-alkyl propylene; mixing the solvents; and heating the solvents. This method requires only one reaction vessel and produces few by-products, therefore is simpler and... Agent: Andrews & Kurth, L.L.P.

20090270633 - Synthesis of 4-[1-(4-cyano phenyl)-(1,2,4-triazol-1-yl)methyl] benzonitrile and 4-[1-(1h-1,2,4-triazol-1-yl)methylene benzonitrile intermediate: The present invention relates to a process for the preparation of 4-[1-(4-cyano phenyl)-1-(1,2,4-triazol-1-yl)methyl]benzonitrile (letrozole), substantially free from its isomeric impurity. The preparation involves reaction of 4-[1-(1H-1,2,4-triazol-1-yl)methylene benzonitrile with 4-fluorobenzonitrile in the presence of an organic solvent and a silicon amine. The present invention also relates to a process for the... Agent: Conley Rose, P.C.

20090270634 - Novel crystal form of 5-hydroxy-1-methylhydantoin: Conventional I-form crystals of 5-hydroxy-1-methylhydantoin contain, remaining therein in a considerable amount, the organic solvent used in a purification step. In contrast, in II-form crystals, the amount of the organic solvent remaining therein is smaller than the detection limit. Namely, the II-form crystals contain substantially no residual organic solvent. The... Agent: Greenblum & Bernstein, P.L.C
