A common heterocyclic compound, 92-30-8,2-(Trifluoromethyl)-10H-phenothiazine, 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. 92-30-8
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).
This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,92-30-8,2-(Trifluoromethyl)-10H-phenothiazine,its application will become more common.
