These common heterocyclic compound, 14227-17-9, name is 2,4,6-Trimethoxyaniline, 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. COA of Formula: C9H13NO3
Intermediate 4 (100 mg) was added to 3 MI of POCl3 at 0 C. 2,4, 6- TNMETHOXYBENZENAMINE (0.13 g) was added and the reaction mixture was stirred for 3 to 5 days. The ice bath was allowed to melt during the first couple of hours. After that, the POC13 suspension was dropped to 200 ml of vigorously stirred diisopropyl ether. The solid material was filtered off and washed with diisopropyl ether. The residue was immediately stirred in ETOAC/SATURATED aqueous NAHCO3 (1/1) (200 ML) for 1 hour. The EtOAc was dried using brine and NA2SO4 successively and evaporated. The residue was purified by preparative TLC using CH2CI2/MEOH (95/5) as the eluent or by precipitation in CH2CLZ/MEOH. Yield: 0.01 g of compound 36 (8%).
The synthetic route of 2,4,6-Trimethoxyaniline has been constantly updated, and we look forward to future research findings.
