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. 33311-29-4, name is 4-(2-Methoxyethoxy)aniline, A new synthetic method of this compound is introduced below., SDS of cas: 33311-29-4
In a 100 mL 3-neck RBF, N-(2-(benzyloxy)-5-nitrophenyl)-2-chloro-5-fluoropyrimidin-4-amine (0.205 g), 4-(2-methoxyethoxy)aniline (0.137 g), Cs2CO3 (0.266 g) and Xantphos (0.032 g) were taken in degassed 1,4-dioxane (8.0 mL) and reaction mixture was degassed under argon for 30 minutes. Palladium acetate (0.013 g) was added to reaction mixture and again it was degassed for 30 minutes. The reaction mixture was heated to 80 C. and stirred for 3.5 h. The reaction was monitored on TLC using hexane:ethyl acetate: (5:5) as mobile phase. After completion, the reaction mixture was allowed to cool at room temperature. The reaction mixture was poured into water and product was extracted with ethyl acetate (3*25 mL). The ethyl acetate layer washed with brine solution, dried over sodium sulfate and concentrated under reduced pressure. Crude material was purified by triturating with diethyl ether to give 0.1 g of N4-(2-(benzyloxy)-5-nitrophenyl)-5-fluoro-N2-(4-(2-methoxyethoxyl)phenyl)pyrimidine-2,4-diamine. 1H NMR: CDCl3 (400 MHz): 3.47 (d, 3H, J=11.6), 3.77 (dd, 2H, J=4.8, 8.8), 4.15 (t, 2H, J=4.8), 5.28 (s, 2H), 6.96 (d, 1H, J=8.8), 7.03 (d, 1H, J=8.8), 7.08 (d, 1H, J=9.2), 7.45 (m, 7H), 7.83 (s, 1H), 7.9 (d, 2H, J=2.8), 8.02 (dd, 1H, J=2.1, 6.8), 9.18 (s, 1H).
The synthetic route of 33311-29-4 has been constantly updated, and we look forward to future research findings.
