Electric Literature of 1421372-67-9, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 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. This compound has unique chemical properties. The synthetic route is as follows.
1) Weigh 200g of the raw material hydrogenation precursor nitro compound, and then add it to a mixture of 4L of methanol and 100g of concentrated hydrochloric acid, stir and dissolve, then add 10g of Pd/C catalyst with Pd content of 10%, stir well and mix to form Material I, the material I is sent to the preheating module 1 of the microchannel reactor for preheating, and after preheating, enters the reaction module group of the microchannel reactor.2) The reaction module group that delivers hydrogen to the microchannel reactor and the step 1) the preheated material I reacts in the reaction module group, wherein: the flow rate of the slurry pump is adjusted so that the flow rate of the material I is 40.0 g/min. The flow rate of the H2 gas flow meter is adjusted to 500 ml/min, the molar ratio of the raw material hydrogenation precursor nitro compound to hydrogen is 1:3.5, the reaction temperature is 90 C, the temperature of the cooling module is 20 C, and the residence time of the reaction is 25s, the reaction pressure is 1.5Mpa, and the collection flows out from the outlet of the cooling module.The reaction solution is subjected to post-treatment, which means that the catalyst is recovered by filtration, and the solvent is distilled off under reduced pressure. The residue is added to 1 L of water, stirred and dissolved, and the pH of the system is adjusted to 9.0 by a NaOH solution having a mass fraction of 20%. 10.0, then join500ml of ethyl acetate was extracted and separated, the organic phase was discarded, the aqueous phase was stirred and crystallized at 10 C for 1 hour, filtered, and the product was washed with a small amount of ethanol, and vacuum dried at 50 C for 8 hours to obtain an oxetinib intermediate. Target product 160.65g, yield85.73%, purity 99.68%.
According to the analysis of related databases, 1421372-67-9, the application of this compound in the production field has become more and more popular.
