The article confers a scalable manufacturing process of Fenspiride HCl. 4-aminomethyl-1-(2-phenylethyl)-piperidin-4-ol is the main building block in Fenspiride HCl synthesis. The reported reagents for 4-aminomethyl-1-(2-phenylethyl)-piperidin-4-ol synthesis are costly, explosive, highly toxic, produce hazardous waste, and also need to be handled with most care. The paper introduces aqueous ammonia as an alternate reagent in Fenspiride HCl and used in 4-aminomethyl-1-(2-phenylethyl)-piperidin-4-ol synthesis. The new green chemistry aspect makes the process environment-friendly and cheaper. It also eliminates toxic, sensitive, and hazardous reagents and makes the process safe on uncomplicated on bulk scale production. The high pure Fenspiride HCl is obtained by following this process and meets the ICH limits with good yield.

Synthesis Of Nanomaterials

The development of reliable and eco-friendly metallic nanoparticles needs some consideration on the chemical procedures involved in the synthesis of nanomaterials. The conventional methods in the production of metallic nanoparticles generate a large amount of hazardous byproducts. Thus, there is a need for ‘green chemistry’ that includes a clean, nontoxic and environment-friendly method of nanoparticle synthesis [1]. As an alternative, biological methods are considered safe and ecologically sound for the nanomaterial fabrication [2]. Therefore, in this review special attention is focused on the biosynthesis of nanoparticles from natural resources as compared as ordinary chemical method. Biosynthesis of nanoparticles using plant is a new development of green nanotechnology beneficial to environmental and to the plant itself. It also plays a significant role in the field of biology and medicine.

MW-assisted treatment of oximinoacetanilides obtained from substituted primary aromatic amines was carried out in conc. H2SO4 medium for 5-10 sec to give cyclic amides (isatins) through intramolecular cyclization by means of electrophilic aromatic substitution. Isatins reacted with thiosemicarbazide under MW-condition gave the corresponding Schiff-bases. The Schiff-bases undergo cyclization in presence of minimal Ac2O under MW-irradiation for 3-4 min to give the spiro-thiadiazoline acetyl derivatives in excellent yield. Keywords:  Microwave-synthesis; Isatins; Schiff-base; spiro-Thiadiazoline; Green chemistry. © 2010 JSR Publications.
