Adding a certain compound to certain chemical reactions, such as: 18368-63-3, 2-Chloro-6-methylpyridine, 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, 18368-63-3, blongs to pyridine-derivatives compound. 18368-63-3
1, 1-dimethylethyl (6-methyl-2-Dyridinyl)acetateTo a stirred solution of tert-butyl acetate (1.013 mL, 7.50 mmol), 2-chloro-6-methylpyridine (638 mg, 5 mmol), chloro(2-di-t-butylphosphino-2′,4′,6′-tri-/’-propyl-1 , 1 ‘-biphenyl)[2-(2- aminoethyl)phenyl]palladium(ll) (34.3 mg, 0.050 mmol) in Toluene (10 mL) at 0 C in a 100-mL round bottom flask under N2 was added a solution of LHMDS (1 M in toluene) (15.00 mL, 15.00 mmol) pre-cooled to 0 C. The reaction was stirred for 30 minutes. LCMS indicated the reaction was complete, so it was poured into ammonium chloride (aqueous, saturated) and water (1 :1 , 40 mL), and extracted with ethyl acetate (3 x 100 mL). The combined organics were dried over sodium sulfate, filtered and concentrated. The residue was purified by flash chromatography (0-25% EtOAc in hexanes) to afford 1 , 1 -dimethylethyl (6-methyl-2-pyridinyl)acetate (918 mg, 4.43 mmol, 89 % yield) as a yellow oil. LC-MS(ES) m/z = 208 [M+H]+. 1 H NMR (400 MHz, DMSO-d6) delta ppm 1.41 (s, 9 H), 2.44 (s, 3 H), 3.68 (s, 1 H), 7.12 (t, J=7.33 Hz, 2 H), 7.64 (t, J=7.71 Hz, 1 H).
With the rapid development of chemical substances, we look forward to future research findings about 18368-63-3.
