92-30-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact.92-30-8,2-(Trifluoromethyl)-10H-phenothiazine, it is a common compound, a new synthetic route is introduced below.
After dissolving 2-(trifluoromethyl)-10H-phenothiazine (2.0 g, 7.48 mmol) in N,N-dimethylformamide (2 mL), 60% sodium hydride (149.70 mg, 3.74 mmol) and 1-bromo-4-chlorobutane (1.16 mL, 10.10 mmol) were added at 0 C. The reactants were heated at 100 C. for 12 hours under reflux. After the reaction was completed, the reaction solution was extracted with ethyl acetate and the organic layer was dried with magnesium sulfate, filtered under reduced pressure and then concentrated under reduced pressure. The target compound (1.52 g) was obtained with a yield of 56.72% by separating the residue by chromatography (ethyl acetate/n-hexane=1/20). 1H NMR (400 MHz, CDCl3): delta 1.89-2.00 (4H, m, 2CH2), 3.40 (1H, t, J=6.02 Hz, CH), 3.54 (1H, t, 6.18 Hz, CH), 3.94 (2H, t, 6.02 Hz, CH2), 6.89 (1H, d, J=8.12 Hz, CH), 6.96 (1H, t, 7.44 Hz, CH) 7.03 (1H, s, CH), 7.13-7.17 (2H, m, 2CH), 7.21 (2H, t, 8.16 Hz, 2CH).
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. 92-30-8, other downstream synthetic routes, hurry up and to see.
