Synthetic Route of 132834-56-1, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 132834-56-1, name is 1-(6-Chloro-5-(trifluoromethyl)pyridin-2-yl)piperazine. This compound has unique chemical properties. The synthetic route is as follows.

To a 16 mm test tube was added; 0.5 mmol of the appropriate alcohol or thiol0.4 mmol of the appropriate 6-chloro 5-trifluoromethyl-2-piperazinylpyridine in DMSO (0.5 mL) 0.65 mmol of K-t-BuO in DMSO (1.0 mL) The reactions were stirred at room temperature for two hours followed by addition of HOAc (1.25 mmol, 75 L). The solvent was evaporated at reduced pressure over night (Speed Vac). The remaining solids were dissolved in water/acetonitrile/HOAc, filtered, and the products were purified with preparative HPLC. Mass detection was obtained by a Micro Mass LCP with electrospray positive ionization mode. The analytical HPLC-chromatograms were performed on a Hewlett Packard 1100 with a 504.6 mm Grom-SIL 100 ODS 0 AB, 3 m column and a 504.6 mm YMC-AQ 5 m column. Different gradients of 0.1% TFA in water and acetonitrile were used and the peaks were detected at 254 nm. The area % under the largest peak was reported as the purity.

According to the analysis of related databases, 132834-56-1, the application of this compound in the production field has become more and more popular.

Adding a certain compound to certain chemical reactions, such as: 132834-56-1, 1-(6-Chloro-5-(trifluoromethyl)pyridin-2-yl)piperazine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 132834-56-1, blongs to pyridine-derivatives compound. Recommanded Product: 132834-56-1

4-(Thiophen-2-yl)butanoic acid (100 ??, 0.68 mmol), HOBt (1 10 mg, 0.816 mmol), TBTU (262 mg, 0.816 mmol), anhydrous triethylamine (152 ??, 1.08 mmol) and anhydrous DMF (2 mL) were placed in an oven-dried Schlenk tube under a nitrogen atmosphere. The resulting solution was stirred at room temperature for 15 minutes. A second Schlenk tube was prepared containing 1-(6-chloro-5- (trifluoromethyl) pyridin-2-yl)piperazine (218 mg, 0.816 mmol) and anhydrous DMF (1 mL) under a nitrogen atmosphere. The resulting solution was stirred until complete dissolution of the piperazine had occurred. The piperazine solution was then transferred, via a cannula, to the first Schlenk tube containing the carboxylic acid. The resulting solution was stirred under nitrogen and monitored by TLC. After 24 hours, the DMF was removed under reduced pressure and the resulting oil was acidified using a 0.1 M HCI solution. The aqueous mixture was extracted with DCM (20 mL, followed by 4 x 10 mL) and the organic layer washed with a saturated sodium bicarbonate solution (3 x 20 mL) and brine (3 x 20 mL). The organic layer was dried over magnesium sulphate and the solvent removed in vacuo. The residue was purified using flash chromatography (3:2, EtOAc:n-hexane) to obtain the desired product in a 68% yield.
