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. 2-(Trifluoromethyl)-10H-phenothiazine, cas is 92-30-8,the thiazines compound, it is a common compound, a new synthetic route is introduced below.
To a mixture of 2-(trifluoromethyl)-l0i7-phenothiazine (5.0 g, 18.726 mmol) and NaH (0.674 g, 28.09 mmol) in DMF (50 mL) was added 2-(bromomethyl)oxirane (3.8 g, 28.09 mmol) at 0 C. The mixture was allowed to slowly warm to rt and was stirred at room temperature overnight. Then the mixture was added to water (100 mL) and extracted with EtOAc (100 mL x 3). The combined organic layers were washed with brine (30 mL), dried over sodium sulfate, and concentrated to dryness. The residue was purified by column chromatography on silica gel (PE/EtOAc = 8/1) to afford compound 2-1 (4.5 g, 75% yield) as a white solid. ‘H NMR (400 MHz, Patent; CAMP4 THERAPEUTICS CORPORATION; BUMCROT, David, A.; SEHGAL, Alfica; HERTZOG, Donald L.; (172 pag.)WO2019/195789; (2019); A1;,
