The synthetic route of 6298-96-0 has been constantly updated, and we look forward to future research findings.
Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 6298-96-0, name is 1-(4-Methoxyphenyl)ethylamine, A new synthetic method of this compound is introduced below., COA of Formula: C9H13NO
B) (4S)-Lambda/-((1 S)-1-r4-(methyloxy)phenyllethyll-3.4-dihvdro-2H-pyranor3.2-lpyridin-4- amine: To a solution of crude 2,3-dihydro-4/-/-pyrano[3,2-]pyridin-4-one (2.43 g) in 1 ,2- dichloroethane was added {(1S)-1-[4-(methyloxy)phenyl]ethyl}amine EPO (2.49 g, 16.5 mmol) and acetic acid (1.4 ml_, 24.5 mmol). The reaction mixture was stirred for 1 hour, then sodium triacetoxyborohydride (5.18 g, 24.4 mmol) was added. The reaction mixture was stirred at room temperature for 16 hours, then diluted with dichloromethane and quenched with saturated aqueous sodium bicarbonate solution. The organic layer was separated and dried over sodium sulfate. Filtration and concentration, followed by flash chromatography (0 to 10% aqueous NH4OH in acetonitrile) provided (4S)- Lambda/-{(1S)-1-[4-(methyloxy)phenyl]ethyl}-3,4-dihydro-2/-/-pyrano[3,2-/j]pyridin-4-amine (1.90 g, 38% two step yield) as a brown oil. 1H NMR (400 MHz, CDCI3) delta 8.15 (dd, J = 3.0, 3.0 Hz, 1 H), 7.35 (d, J = 8.6 Hz, 2 H), 7.07 (d, J = 2.8 Hz, 2 H), 6.86 (d, J = 8.7 Hz, 2 H), 4.19 (ddd, J = 11.0, 7.7, 3.3 Hz, 1 H), 4.07 (q, J = 6.5 Hz, 1 H), 4.00 (ddd, J = 11.1 , 7.3, 3.5 Hz, 1 H), 3.91 (t, J = 5.7 Hz, 1 H), 3.80 (s, 3 H), 2.32 (br, 1 H), 1.70 (m, 2 H), 1.44 (d, J = 6.6 Hz, 3 H).
