As a common heterocyclic compound, it belongs to thiazines compound, name is 2-(Trifluoromethyl)-10H-phenothiazine, and cas is 92-30-8, its synthesis route is as follows.,92-30-8
II-4 (20g, 75mmol) a 100mL reaction flask was added DMF (60mL) was stirred and dissolved, was added potassium carbonate (15.5g, 113mmol), stirred at 60¡ãC , portionwise Intermediate III-5 (17.5g , 79mmol), the reaction after 1h, TLC analysis showed completion of the reaction (developing solvent, ethyl acetate: petroleum ether = 1: 3). The reaction solution was poured into 200ml cold water, with stirring, solid precipitated out.Filter cake was washed with water, and dried to give brown crude solid.The crude product was recrystallized from ethanol to give slightly yellow solid 30.0g. Purity 98.8percent (HPLC normalization method), a yield of 88.3percent.ESI-MS ([M + H] +): 453.0.
With the complex challenges of chemical substances, we look forward to future research findings about 92-30-8,belong thiazines compound
