Adding a certain compound to certain chemical reactions, such as: 39538-68-6, name is 2-Methoxy-4-methylaniline, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 39538-68-6, Recommanded Product: 2-Methoxy-4-methylaniline
To a test tube with a magnet stirrer bar was added N-methyl-2-{[2-(1 /-/-1 , 2, 4-triazol-1 – yl)-5- (trifluoromethyl) pyrimidin-4-yl] amino} benzamide (Compound 6, 0.200 g, 0.550 mmol) and 2-methoxy-4-methyl aniline (0.083 g, 0.606 mmol, 1 .1 eq.). To the mixture, trimethylacetic acid (1 .0 g, 9.791 mmol, 17.8 eq.) was added and the resulting suspension was stirred and heated in an oil bath set at 130 C. The progress of the reaction was monitored by HPLC. After 29 h the reaction mixture was cooled to room temperature, quenched with 3 N NaOH (3.9 ml_, 1 1 .75 mmol, 21 eq.) and diluted with toluene. Insoluble solids were filtered off and the layers were separated. The organic phase was washed with water and brine and then concentrated under vacuum. The residue was stirred in a mixture of heptanes and dichloromethane at room temperature and the resultant solids were collected by filtration and rinsed with heptane. The damp solid was dried under high vacuum to give 1 18 mg of the desired product as a pale solid. 1 H NMR {CDCI3}: 5(ppm) 10.75 (br s, 1 H, NH), 8.46 (d, J = 8.0 Hz, 1 H, ArH ), 8.36 (s, 1 H, ArH), 8.14 (d, J = 8.0 Hz, 1 H, ArH), 7.64 (br s, 1 H, NH), 7.45 – 7.49 (m, 2 H, 2X ArH), 7.13 (t, J = 8.0 Hz, 1 H, ArH), 6.72 (s, 1 H, ArH), 6.68 (d, J = 8.0 Hz, 1 H, ArH), 6.18 (br s, 1 H, NH), 3.88 (s, 3 H, OCH3), 3.02 (d, J = 4.0 Hz, 3 H, NCH3), 2.34 (s, 3 H, CH3). 19F NMR {CDC }: 5(ppm) 61 .4. HPLC: 97.2% area, Rt = 7.34 min.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Methoxy-4-methylaniline, other downstream synthetic routes, hurry up and to see.
