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. H NMR (300 MHz, CDCI3) ? 7.66 (d, J = 8.7 Hz, 1 H), 7.10 (dd, J = 5.1 Hz, J = 1 .2 Hz, 1 H), 6.92-6.89 (m, 1 H), 6.80-3.79 (m, 1 H), 6.46 (d, J = 8.7 Hz, 1 H), 3.72- 3.67 (m, 4H), 3.97-3.57 (m, 2H), 3.52-3.49 (m, 2H), 2.88 (t, J = 7.5 Hz, 2H), 2.31 (t, J = 7.5 Hz, 2H), 2.09-1.99 (m, J = 7.2 Hz, 2H). 3C NMR (75 MHz, CDCI3) 171.2, 158.9, 147.5, 144.2, 137.6 (q, J = 3.75 Hz), 126.8, 124.5, 123.2, 1 17.8 (q, J = 268.5 Hz), 1 12.0 (q, J = 33 Hz), 103.3, 44.7, 44.5, 44.1 , 40.7, 31 .9, 29.2, 26.9.
