Synthetic Route of 85953-29-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 85953-29-3, name is Methyl 2-chloro-4-fluorobenzoate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Step 1 : tert-butyl 4-((l-(3-chloro-4-(methoxycarbonyl)phenyl)piperidin-4-yl)methyl)piperidine- 1-carboxylate A mixture of methyl 2-chloro-4-fluorobenzoate (367 mg, 1.95 mmol), tert-butyl 4-(piperidin-4- y lmethyl)piperi dine- 1-carboxy late (500 mg, 1.77 mmol), and CS2CO3 (1269 mg, 3.89 mmol) in DMSO (8.8 ml) was degassed by bubbling with N2 and heated at 120C for lh under microwave condition. The mixture was diluted with EtOAc-H20, and the aq. layer was extracted with EtOAc (3x). The combined organic fractions were dried over Na2SC>4, filtered and the solvent was evaporated under reduced pressure. The reaction mixture was purified by ISCO column chromatography (silica gel ISCO 40 g prepacked column, eluting with 0-100% EtOAc/Hexane) to give the title compound (578 mg). LCMS m/z (M+H): Calc’d 451.2, found 451.4.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 2-chloro-4-fluorobenzoate, other downstream synthetic routes, hurry up and to see.
