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. 39959-51-8, name is (2-Iodophenyl)methanamine, A new synthetic method of this compound is introduced below., SDS of cas: 39959-51-8
Example 14 N4-[(trans-4-aminocyclohexyl)methyl]-N2-{2-[(2-aminophenyl)thio]benzyl}-5-nitropyrimidine-2,4-diamine To a solution of {4-[(2-chloro-5-nitro-pyrimidin-4-ylamino)-methyl]-cyclohexyl}-carbamic acid tert-butyl ester (100 mg, 0.26 mmol) in a mixture of CH2Cl2 (2 mL) and DMF (1 mL) were added 2-iodobenzylamine (192 mg, 0.82 mmol) and DIPEA (135 muL, 1.04 mmol). The reaction mixture was stirred at room temperature for 16 h and concentrated in vacuo. The resulting residue was diluted with EtOAc and washed with water (*3) and then with brine. The organic phase was dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by silica gel preparative TLC using 98:2 CH2Cl2:MeOH as an eluent to afford 97 mg (64%) of (4-{[2-(2-iodo-benzylamino)-5-nitro-pyrimidin-4-ylamino]-methyl}-cyclohexyl)-carbamic acid tert-butyl ester.
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.
