Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.1771-18-2, name is :2-Methoxyphenothiazine, below Introduce a new synthetic route.. 1771-18-2

38.1) 2-Methoxy-10H-phenothiazine-1-carbaldehyde: 4.6 g (20 mmol) of 2-methoxy-10H-phenothiazine are dissolved, under an argon atmosphere, in a three-necked flask, containing 140 ml anhydrous ethyl ether. 20 ml (50 mmol) of a solution of nBuLi (2.5 M) in hexane is then added dropwise, at 20 C. The reaction mixture is agitated for 3 hours at 20 C. before the dropwise addition of 6.2 ml (80 mmol) of anhydrous DMF. Agitation is maintained for another 15 hours at 20 C. The whole is then poured into 150 ml ice-cooled water and the product is extracted twice using 200 ml of ethyl acetate. The organic solution is washed with 100 ml of salt water, dried over MgSO4, filtered and concentrated under vacuum. The evaporation residue is taken up in diisopropyl ether, filtered and dried to produce a red solid with a yield of 30%. Melting point: 155-160 C., 1771-18-2

According to the analysis of related databases, 1771-18-2, the application of this compound in the production field has become more and more popular.

An elementary termolecular reaction involves the simultaneous collision of three atoms, 1771-18-2, molecules, or ions. Here is a downstream synthesis route of the compound 1771-18-2, name is :2-Methoxyphenothiazine

Step a 4-(3′-indolyl)-1-[1″-(2′”-methoxy-10′”-phenothiazinyl) -2″-methyl-3″-propionyl]-piperidine hydrochloride A mixture of 23 g of 2methoxy-phenothiazine, 21 g of methacryloyl chloride and 120 ml of toluene was refluxed for 3 hours and was then cooled and washed with 250 ml of N sodium hydroxide. The organic phase was decanted and the aqueous phase was washed twice with 50 ml of toluene. The combined organic phases were washed with water, dried over magnesium sulfate, treated with carbon black and evaporated to dryness to obtain 29.6 g of 2-methoxy-10-(alpha-methyl acryloyl)-phenothiazine melting at 91-92 C., 1771-18-2

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 1771-18-2.
