Application of 1535-75-7, The chemical industry reduces the impact on the environment during synthesis 1535-75-7, name is 2-(Trifluoromethoxy)aniline, I believe this compound will play a more active role in future production and life.
Synthesis of2-chloro-5-methoxy-N-(2-(trifluoromethoxy) phenyl) pyrimidin-4-amine [0342] To a stirred solution of 2, 4-dichloro-5-methoxypyrimidine (5 g, 28.08 mmol) in tertiary butyl alcohol (35 mL) under argon atmosphere were added 2-(trifluoromethoxy) aniline (4 g, 22.47 mmol) and diisopropylethylamine (35 mL) at RT. The reaction mixture was stirred at 160 C for 48 h in a sealed tube. After completion of the reaction (monitored by TLC), the volatile components were removed in vacuo. The crude material was purified by silica gel column chromatography using 10% EtOAc:hexanes to afford 2-chloro-5-methoxy- N-(2-(trifluoromethoxy) phenyl) pyrimidin-4-amine (2 g, 22%) as a colorless syrup. 1H-NMR (CDCls, 400 MHz): delta 8.64 (d, 1H), 7.79 (s, 1H), 7.72 (br s, 1H), 7.38 (t, 1H), 7.30-7.27 (m, 1H), 7.10-7.07 (m, 1H), 4.00 (s, 3H); LC-MS: 320.3 (M+l); (column; X Select CSH C-18 (50 x 3.0 mm, 3.5 muiotaeta); RT 4.63 min. 0.05% Aq TFA: ACN; 0.80 ml/min); TLC: 15% EtOAc:hexanes {Rf. 0.3).
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-(Trifluoromethoxy)aniline, other downstream synthetic routes, hurry up and to see.
