92-30-8, 2-(Trifluoromethyl)-10H-phenothiazine is a thiazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: To a solution of hydroxy compounds, sulfhydryl compounds oramino compounds (1.0 eq) and propargyl bromide (1.2 eq) inacetone (20 ml) was added NaOH (1.5 eq), the mixturewas refluxedfor about 6 h. Upon completion, the residue was purified withcolumn chromatography (hexane:EtOAc 7:1) to obtain analogue13a~13m. Sulfonyl chlorides (1.0 eq) and propynylamine (1.2 eq) inCH2Cl2 (20 ml) was added Et3N (1.5 eq), the mixture was stirred atroom temperature for about 6 h. Upon completion, the residue waspurified with column chromatography (hexane:EtOAc 9:1) toobtain analogue 13n~13o.

92-30-8 2-(Trifluoromethyl)-10H-phenothiazine 7082, athiazines compound, is more and more widely used in various.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.92-30-8,2-(Trifluoromethyl)-10H-phenothiazine,as a common compound, the synthetic route is as follows.

2-Trifluoromethylphenothiazine (2.00 g, 7.4831 mmol) was placed in a 500 mL flask, THF (100 mL) dried overanhydrous K2CO3 was added, and then 60% NaH was added sequentially under N2 protection. Mineral oil(1.1973 g, 29.9323 mmol) and 1-bromo-3-chloropropane (2.9601 mL, 29.9323 mmol) were refluxed overnightat a bath temperature of 65 C. After cooling to room temperature, the reaction mixture was poured into EtOAc EtOAc (EtOAc)EtOAc. Ethylacetate (50 mL) was added to dissolve, and silica gel powder (20 g) was added to the solution to dryness, and theresidue was applied to a silica gel column, eluted with ethyl acetate and petroleum ether, and the product wascollected, dried, and dried in vacuo. Product 2-10 (4.9444 g, yield 69.8%).

As the paragraph descriping shows that 92-30-8 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.92-30-8,2-(Trifluoromethyl)-10H-phenothiazine,as a common compound, the synthetic route is as follows.

General procedure: A stirred mixture of phenothiazine (100 mg, 0.5 mmol),3,5-dimethylphenol (183 mg, 1.5 mmol), and K2CO3 (69 mg,0.5 mmol) in ODCB (1.5 mL) was heated to 130 oC for 6 h under O2 balloon atmosphere. After the usual aqueous extractive workup and column chromatographic purification process (hexanes/EtOAc, 20:1) para-3a (103 mg, 64percent) and ortho-3a (34 mg, 21percent) were obtained as white solids. Other compounds were synthesized similarly, and the spectroscopic data of 3a-3m and the sulfoxide of 3g are as follows.

As the paragraph descriping shows that 92-30-8 is playing an increasingly important role.
