369-26-6, name is Methyl 3-amino-4-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. 369-26-6
Step 1 : 3-Amino-N-(2-tert-butoxyethyl)-4-fluorobenzamide A mixture comprising 2-tert-butoxyethanamine (1 .2 g, 5.12 mmol, 50percentw/w) and methyl 3-amino-4-fluorobenzoate (0.866 g, 5.12 mmol) in THF (10 ml) was treated with TBD (0.713 g, 5.12 mmol) and heated at 90 ¡ãC for 16 hrs. After cooling to RT, the solvent was removed in vacuo and the residue was partitioned between water and EtOAc. The organic portion was separated and washed with 10percent aq citric acid (x 2), NaHC03(sat. aq), brine, dried (MgS04) and concentrated in vacuo. Purification of the crude product by chromatography on silica eluting with 0-100percent EtOAc in iso- hexane afforded the title compound as a clear oil;LC-MS: Rt 1.09 mins; MS m/z 255 [M+H]+; Method 2minl_C_v003
Statistics shows that 369-26-6 is playing an increasingly important role. we look forward to future research findings about Methyl 3-amino-4-fluorobenzoate.
