Reference of 6298-96-0, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6298-96-0, name is 1-(4-Methoxyphenyl)ethylamine belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Examrle 22-[(S)-1 -(4-methoxyphenyl)-ethylamino]-cyclopent-1 -ene-carboxylic acid methylester(compound of formula (IV) wherein Ar = 4-methoxyphenyl, R1 = CO2Me) 10.37 g (70.0 mmol) of 2-oxo-cyclopentane-carboxylic acid methylester (purity 96%, Aldrich) were dissolved in 30 ml of toluene and 10.00 g (65.5 mmol) of (S)-1 -(4- methoxyphenyl)-ethylamine (purity >99%, BASE) were stirred under argon for 12 hours at ca. 25C. Water was completely removed by evaporation of toluene (3 x 50 ml) andthe product was dried at 80C/i mbar to give 18.1 g (100%) of the title product asyellow oil.LC-MS: MH 276;1H NMR: 1 .40 (d, 3H, Me), 1 .65 (m, 2H, H-4), 2.25, 2.37, 2.62 (3m, 4H, H-3, H-5), 3.57(5, 3H, CO2Me), 3.73 (5, 3H, OMe), 4.60 (m, 1 H, CHN), 6,90, 7.20 (2m, 4H, Ar-H), 7.70(d, 1H, NH).
The synthetic route of 1-(4-Methoxyphenyl)ethylamine has been constantly updated, and we look forward to future research findings.
