These common heterocyclic compound, 67344-77-8, name is 1-(3-Bromophenyl)-N-methylmethanamine, 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. SDS of cas: 67344-77-8
To a solution of 1-(3-bromophenyl)-N-methylmethanamine (12.0 g) and N-(tert-butoxycarbonyl)glycine (11.5 g) in dichloroethane (80 ml) were added HOBt (9.7 g) and WSC hydrochloride (13.7 g), followed by stirring at room temperature overnight. To the reaction mixture was added a saturated aqueous sodium hydrogen carbonate solution, followed by extraction with CHCl3. The mixture was dried over Na2SO4 and then concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (CHCl3/MeOH) to obtain tert-butyl {2-[(3-bromobenzyl)amino]-2-oxoethyl}carbamate (21.3 g).
The synthetic route of 1-(3-Bromophenyl)-N-methylmethanamine has been constantly updated, and we look forward to future research findings.
