85064-61-5,85064-61-5, Tetrahydropyranyl-4-acetic acid is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
The starting materials are prepared as follows:; a) N-{2-[(2S,5R)-5-[4-(3-Methoxypropyn-3,4-dihvdro-2H-benzo[1 ,4loxazin-6- ylmethoxyl-1 -(toluene-4-sulphonyl)piperidin-2-yll-1 , 1 -dimethylethyl)-2- (tetrahydropyran-4-yl)acetamide; A solution of 0.511 mmol of tetrahydropyranyl-4-acetic acid [85064-61-5] in 5 ml of dichloromethane is treated with 1.023 mmol of 1-chloro-N,N-2-trimethylpropenyl- amine. The reaction mixture is stirred at room temperature for 1.5 hours. In a second flask, a solution of 0.341 mmol of 2-[(2S,5R)-5-[4-(3-methoxypropyl)-3,4-dihydro-2H- benzo[1 ,4]oxazin-6-ylmethoxy]-1 -(toluene-4-sulphonyl)piperidin-2-yl]-1 , 1 -dimethyl- ethylamine in 10 ml of dichloromethane are treated with 1.023 mmol of triethylamine, and cooled to 00C. The solution of acid chloride is added dropwise to this second flask, and the reaction mixture is stirred at room temperature for 2 hours. Water is added, and the aqueous phase is extracted with dichloromethane (3X). The combined organic extracts are dried over sodium sulphate, concentrated and purified by flash chromatography (Sitheta2 60F) to afford the title compound as a dark yellow resin. Rf = 0.20 (dichloromethane-methanol-conc ammonia); Rt = 4.94 (gradient I).
As the paragraph descriping shows that 85064-61-5 is playing an increasingly important role.
