Adding a certain compound to certain chemical reactions, such as: 764-48-7, Ethylene Glycol Vinyl Ether, 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, category: alcohols-buliding-blocks, blongs to alcohols-buliding-blocks compound. category: alcohols-buliding-blocks
10098] Compound 2, 1 -(6-(7-azabicyclo[2.2. 1]heptan-7- yl)naphthalen-2-yl)ethanone, was synthesized by the inventors.10099] Specifically, Compound 2c obtained in Example1-3 (184 mg, 0.61 mmol), palladium(II) acetate (Pd(OAc)2,6.8 mg, 0.03 mmol), diphenylphosphinopropane (DPPP,25.2 mg, 0.06 mmol), and ethyleneglycol (1.5 mE) were added to an oven-dried flask with two necks and charged with argon gas. Afier oxygen present in the mixture was removed by adding the argon gas to the mixture, ethyleneglycol vinyl ether (279 pL, 1.53 mmol) and Et3N (255 pL, 1.83 mmol) obtained by distillation were sequentially added thereto. The resulting mixture was stirred at 145 C. for 5 hours using a silicone oil container. The mixture was cooled to room temperature, and stirred with a 6N hydrochloric acid (HC1) aqueous solution (4 mE) at 60 C. for 4 hours. The mixture was cooled to room temperature, and diluted with ethyl acetate (100 mE). An organic layer was washed with water (50 mE), a 5% sodium bicarbonate aqueous solution (50 mE), and a saturated saline solution (50 mE) and dehydrated with anhydrous sodium sulfate (10 g). The solvent was removed under a reduced pressure condition of 40 mbar, and the resulting product was purified by colunm chromatography through a silica gel (Merck-silicagel 60, 230-400 mesh; using EtOAc/hexane as a developer), thereby obtaining a yellow solid, Compound 2 (100 mg, 62%). By further purification using recrystallization (using 3% CH2C12/hexane as a solvent), a yellow solid, Compound 2 (32 mg, 20%), was obtained.10100] ?H NMR (CDC13, 300 MHz, 298 K, oe): 8.32 (d, J=1.5 Hz, 1H), 7.93 (dd, J=8.7, 1.8 Hz, 1H), 7.78 (d, J=9.0 Hz, 1H), 7.64 (d, J=8.7 Hz, 1H), 7.24 (dd, J=8.7, 2.1 Hz, 1H), 7.11 (d, J=2.4 Hz, 1H), 4.37-4.34 (m, 2H), 2.67 (s, 3H),1.87-1.84 (m, 4H), 1.54-1.5 (m, 4H); ?3C NMR (CDC13, 75 MHz, 298 K, oe): 198.0, 148.6, 137.7, 131.9, 131.0, 130.4, 127.0, 126.7, 124.7, 119.8, 110.3, 58.3, 29.0, 26.7; IR (KBr, cm?): 1670; HRMS: mlz calcd for C,8H,9N0 [M] 265. 1467, C,8H2QNO [MH] 266.1545; found 265.1467 [M],266.1547 [MW]; mp: 118-120 C.
The synthetic route of 764-48-7 has been constantly updated, and we look forward to future research findings.
