Electric Literature of 702-24-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 702-24-9, name is 4-Methoxy-N-methylbenzylamine, This compound has unique chemical properties. The synthetic route is as follows.
A solution of 8-bromo-6-chloroimidazo[l,2-b]pyridazine-3-carbonitrile (2.82 g, 13.23 mmol), l-(4-methoxyphenyl)-N-methylmethanamine (2.00 g, 13.23 mmol) and diisopropylethylamine (4.62 mL, 26.5 mmol) in tetrahydrofuran (25 mL) was heated to 60 °C for 3 hours and then concentrated to dryness. The crude product was triturated with methanol and filtered rinsing with methanol. The solid was dried and collected as is (3.85 g, 89percent yield). NMR (400MHz, CHLOROFORM-d) delta 7.99 (s, 1H), 7.16 (d, J=8.8 Hz, 2H), 6.93 – 6.82 (m, 2H), 6.12 (s, 1H), 5.45 (br. s., 2H), 3.80 (s, 3H), 3.20 (br. s., 3H). LC retention time 1.05 min [J]. MS (E+) m/z: 328 (MH+).
The chemical industry reduces the impact on the environment during synthesis 4-Methoxy-N-methylbenzylamine. I believe this compound will play a more active role in future production and life.
