Application of 1421372-67-9, 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. 1421372-67-9, name is N1-(2-(Dimethylamino)ethyl)-5-methoxy-N1-methyl-N4-(4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl)-2-nitrobenzene-1,4-diamine. A new synthetic method of this compound is introduced below.
Under nitrogen protection,928 ml of methanol was added to a 2 L four-necked flask,Then, 92.8 g of the compound represented by the formula (III)Stirring,18.6g was added Raney nickel (water-wet product)8 at atmospheric pressure under hydrogenation,Reaction temperature 25 ,The reaction was carried out for 6 hours.Filtered by rotary evaporation to yield 82.6 g of gray solid, yield: 95.0%
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1421372-67-9, N1-(2-(Dimethylamino)ethyl)-5-methoxy-N1-methyl-N4-(4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl)-2-nitrobenzene-1,4-diamine, and friends who are interested can also refer to it.
