Synthetic Route of 698-19-1, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 698-19-1 name is 1-(2-Bromophenyl)-N-methylmethanamine, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Preparation of ferf-butyl 2-bromobenzyl(methyl)carbamate (59). 58 59 A solution of compound 58 (2.0 g, 10.0 mmol) and Boc20 (2.29 g, 10.5 mmol) in THF (40 mL) was stirred at RT for 16 hours. The mixture was then concentrated in vacuo. The crude product was purified by flash column chromatography over silica gel, which was eluted with 10% EtOAc in heptanes, and yielded compound 59 as a colorless oil (2.8 g, 95% yield). 1H NMR (400 MHz, CDCI3) delta 7.54 (d, 1 H), 7.30 (t, 1 H), 7.13 (m, 2 H), 4.53 (br d, 2 H), 2.87 (br s, 3 H), 1.46 (br d, 9 H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-(2-Bromophenyl)-N-methylmethanamine, and friends who are interested can also refer to it.
