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. 914306-50-6, name is 1-(2,6-Diisopropylphenyl)-2-phenyl-1H-imidazole, A new synthetic method of this compound is introduced below., Product Details of 914306-50-6
(Step 3) Into a three-head flask, there were put 2.8 g of the intermediate body C obtained in Step 2, 1.6 g of an intermediate body D, and 50 ml of ethylene glycol, and this mixture was heated and stirred for 7 hours at 150 C. under a nitrogen atmosphere. Precipitated crystals were obtained by filtration, and the crystals obtained by the filtration were washed by methanol, and thereafter, were separated and purified by silica gel chromatography, whereby 0.7 g of the DP-1 was obtained. A structure of the compound example DP-1 was confirmed by MASS spectrum and 1H-NMR. MASS spectrum (ESI): m/z=1179 [M+] 1H-NMR (CD2CI2, 400 MHz) delta: 7.71 (2H, d, J=28.3 Hz), 7.42 (1H, t, J=28.3 Hz), 7.33-7.57 (6H, m), 7.34 (4H, t, J-33.2 Hz), 6.96 (2H, 5), 6.81-6.86 (6H, m), 6.69 (2H, d, J=33.2 Hz), 6.56-6.60 (2H, m), 6.44 (1H, t, J=23.4 Hz), 6.38 (2H, d, J=17.6 Hz), 6.32 (1H, d, J=23.4 Hz), 6.16 (2H, d, J=44.9 Hz), 2.65-2.80 (3H, m, CH of iso-Pr), 2.29-2.41 (3H, m, CH of iso-Pr), 1.26 (3H, d, J=26.3 Hz, CH3 of iso-Pr), 1.21 (6H, d, J=20.5 Hz, CH3 of iso-Pr), 0.92-1.08 (m, 27H, CH3 of iso-Pr)
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.
