Reference of 366-99-4, These common heterocyclic compound, 366-99-4, name is 3-Fluoro-4-methoxyaniline, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Cyclopentanone (16.8 g, 200 mmol), Acetic acid (1.8 g, 30 mmol), and Sodium triacetoxyborohydride (6.36 g, 30 mmol) were added to a solution of 3-Fluoro-4-methoxyaniline (2.82 g, 20 mmol) in DCM (120 mL) and the mixture was stirred at RT for 12 hr. Water was added to quench the reaction and the mixture was extracted with DCM. The solvent was removed under and the residue was purified by silica gel chromatography to afford N-Cyclopentyl-3-fluoro-4-methoxyaniline (2.0 g, 48percent yield). MS m/z=210 [M+H].
The synthetic route of 366-99-4 has been constantly updated, and we look forward to future research findings.
