394-35-4, name is Methyl 2-fluorobenzoate, belongs to esters-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of Methyl 2-fluorobenzoate
Preparation Example 196 To a solution of 1.0 g of tert-butyl (3S)-piperidin-3-yl carbamate in 20 ml of DMF were added 0.77 ml of methyl 2-fluorobenzoate and 1.4 g of potassium carbonate, followed by stirring at 130° C. overnight. After leaving to be cooled, to the reaction mixture were added water and ethyl acetate to carry out a layer separation operation. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to obtain 590 mg of methyl 2-{(3S)-3-[(tert-butoxycarbonyl)amino]piperidin-1-yl}benzoate.
The synthetic route of 394-35-4 has been constantly updated, and we look forward to future research findings.
