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. 92248-06-1, name is Bis(3-methoxyphenyl)amine, A new synthetic method of this compound is introduced below., Product Details of 92248-06-1
EXAMPLE 5 N,N-Di(3-methoxyphenyl)-7-(benzothiazol-2-yl)-9,9-diethyl-fluoren-2-amine A mixture of 7-benzothiazol-2-yl-9,9-diethyl-2-bromofluorene (Example 4; 10.85 g, 25 mmol), 3,3′-dimethoxydiphenylamine (6.87 g, 30 mmol) and toluene (100 mL) was azeotroped dry under nitrogen and cooled. Bis(dibenzylidene acetone)palladium (0) (0.28 g, 0.49 mmol), bis(diphenylphosphino)ferrocene (0.25 g, 0.45 mmol) and sodium-t-butoxide (3.5 g, 36.4 mmol) were then added and the mixture was heated to 100 C. After 24 hours, the mixture was cooled, diluted with toluene and filtered. The filtrate was washed with water, dried and concentrated. The residue was chromatographed over silica gel. Elution with toluene-heptane (3:1) mixture gave the product, which was recrystallized from a mixture of toluene-heptane, m.p. 178-179.5 C., 11.13 g (76% yield). 1H NMR (CDCl3) delta ppm: 0.35-0.41 (t, 6H), 1.91-2.14 (m, 4H), 3.69 (s, 6H), 6.54-6.74, 7.05-7.68, 7.84-8.10 (m, 18H). 13C NMR (CDCl3) delta ppm: 8.61, 32.66, 55.18, 56.44 (sp3C), 108.62, 109.77, 116.66, 119.16, 119.42, 121.00, 121.44, 121.52, 122.94, 123.77, 124.95, 126.28, 127.28, 129.82, 131.55, 134.91, 135.61, 144.48, 147.84, 148.94, 150.67, 151.99, 154.24, 160.46, 168.81 (sp2C). Anal. Calcd for C38H34N2O2S: C, 78.33%; H, 5.88%; N, 4.81%; S, 5.49%. Found: C, 78.26%; H, 5.96%; N, 4.68%; S 5.47%.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
