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
1 -Bromo-3-chloropropane (37.68 g, 200 mmol) was added to 2-(trifluoromethyl)- l0i7-phenothiazine (26.7 g, 100 mmol) and Cs2CC>3 (65.6 g, 200 mmol) in DMF (130 mL). The mixture was stirred at 30 C for 48 h and then heated to 80 C for 2 h. The mixture was cooled to rt then H20 was added. The mixture was extracted with PE three times (200 mL x 3). The combined organic phase was washed with brine, dried over Na2S04, and concentrated in vacuo. The residue was purified by column chromatography (PE 100%, PE:EtOAc = 60: 1) to get 10.8 g pure and 19 g crude. LC-MS: Rt = 2.29 min; ESI, m/z 344 [M+l]+.
This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,2-(Trifluoromethyl)-10H-phenothiazine,92-30-8,its application will become more common.
