Related Products of 4152-90-3, These common heterocyclic compound, 4152-90-3, name is (3-Chlorophenyl)methanamine, 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.
N-(3-Chlorobenzyl)-5-fluoro-2-nitrobenzenamine:; 2,4-Difluoronitrobenzene (2.9 g, 18.1 mmol), 3-chlorobenzylarnine (2.6 g, 18.1 mmol) 0 and LambdazetaiV-diisopropylethylamine (2.4 g, 18.1 mmol) were stirred in acetonitrile (25 mL) at room temperature for 2 hours. The solvent was evaporated and the crude mixture was dissolved in dichloromethane and washed with water. The dichloromethane was evaporated in vacuo to collect the title compound (4.8 g, 95 percent yield). 1H NMR (400 MHz, CDCl3): delta 8.55 (s, IH), 8.25 (dd, IH), 7.32-7.21 (m, 4H), 6.41 (m, 2H), 4.50 (d, 2H).
The synthetic route of 4152-90-3 has been constantly updated, and we look forward to future research findings.
