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. 72235-58-6, name is (4-Chloro-3-fluorophenyl)methanamine, A new synthetic method of this compound is introduced below., name: (4-Chloro-3-fluorophenyl)methanamine

4-{[(2,4-Dimethoxybenzyl)(l,3-thiazol-2-yl)amino]sulfonyl}-3-fluorobenzoic acid (Preparation 10, 75mg, 0.166mmol, leq), Et3N (36mg, 0.36mmol, 2.2eq), 2-(lH-benzotriazol- l-yl)-l,l,l,3,tetramethyluronium tetrafluoroborate (TBTU, 66mg, 0.206mmol, 1.24eq) and A- chloro-3-fluorobenzylamine (48mg, 0.301mmol, 1.81eq) were combined in THF (3ml) and the reaction mixture stirred at room temperature for 18 hours. The solvent was evaporated and the residue dissolved in DCM:TFA (2ml: 2ml), the reaction mixture was stirred at room temperature for 2 hours. Water (4ml) was added and the mixture was passed through a phase separation cartridge. The DCM was collected, washed with saturated sodium hydrogen carbonate, dried over sodium sulphate, filtered and evaporated in vacuo. The crude material was triturated with DCM then purified further by preparative HPLC to yield the title compound.[0358] LCMS Rt= 3.14-3.18 min. MS m/z 443 [MH]+

The synthetic route of 72235-58-6 has been constantly updated, and we look forward to future research findings.
