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
A mixture of 1-1 [2-(trifluoromethyl)-l0i7-phenothiazine] (300 mg, 1.12 mmol), 1- bromo-4-chlorobutane (391 mg, 2.28 mmol) and CS2CO3 (1.04 g, 3.19 mmol) in DMF (15 mL) was stirred at rt overnight. The mixture was poured into cool water (20 mL) and extracted with EtOAc (15 mL x 3). The combined organic extracts were washed with brine, dried over NaiSCE. fdtered and concentrated under reduced pressure. The residue was purified by column chromatography (petrol ether: EtOAc =10: 1) to provide a yellow solid (240 mg, 60% yield). LC-MS: Rt = 2.30 min; ESI, m/r 358 [M + 1] +
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.
