20196-21-8, A common heterocyclic compound, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route., 20196-21-8
Preparation 5 4-(4-Trifluoromethylphenyl)-thiomorpholin-3-one. A mixture of thiomorpholin-3-one (500 mg, 4.27 mmol), 4-trifluoromethyl-1-iodobenzene (1.25 mL, 8.5 mmol) and copper metal (814 mg, 12.8 mmol) was heated in a sealed glass tube at 185-200 C. for 18 hours. The residue was then purified by flash chromatography to give 260 mg of the title product as a white solid. M.p. 85-87 C. Mass spectrum 262 (M-1). 1H-NMR (CDCl3, 400 MHz) d 7.62 (2H, d), 7.37 (2H, d), 3.97 (2H, t), 3.43 (2H, s), 3.01 (2H, t).
The chemical industry reduces the impact on the environment during synthesis, 20196-21-8, I believe this compound will play a more active role in future production and life.
