Abstract
The present invention provides an improved process for preparation of organic compounds represented by Formula-Z; wherein effectively minimising the formation of dehalogenated by-products is achieved. In the process, the reduction is carried out using suitable reducing agent; more preferably Lithium Aluminium Hydride (LAH) in a solvent system, wherein at least one of the solvent is selected from halogenated solvents, which acts as co-solvent. The process of the present invention is useful for minimising of the formation of dehalogenated by-products during synthesis of various active pharmaceutical ingredients such as Paroxetine Hydrochloride, Cinacalcet, Eletriptan and Asenapine.
