With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.59801-62-6,Thiomorpholine 1,1-dioxide hydrochloride,as a common compound, the synthetic route is as follows.,59801-62-6
After 158 mg of cis-(+)-2-(4-Bromomethylbenzyl)-4-(3,4-dimethoxyphenyl)-4a,5,8,8a-tetrahydro-2H-phthalazin-1 -one obtained in the step 1 in Example 2-1 was dissolved in 20 mL of N,N-Dimethylformamide, 1.10 g of 1,1,-Dioxidothiomorpholine hydrochloride and 1.77 g of Potassium carbonate were added thereto and then the reaction liquid was stirred at room temperature for 9 hours. Water was added to the reaction liquid, and the reaction liquid was subjected to extraction procedure with ethyl acetate. The organic layer was washed with water and saturated saline and dried with anhydrous Magnesium sulfate, and the solvent was evaporated in vacuo. The crude product was purified through silica gel column chromatography to obtain 827 mg of the objective compound as a white amorphous substance. 1H-NMR(CDCl3) delta: 1.9-2.3(3H,m), 2.83(1H,t), 2.9-3.1(9H,m), 3.35(1H,ddd), 3.61(2H,s), 3.92(3H,s), 3.93(3H,s), 5.02(2H,dd), 5.73(2H,m), 6.86(1H,d), 7.2-7.3(3H,m), 7.36(2H,d), 7.46(1H,d) Specific rotation [alpha]D25 = 418.59 (c = 1.0, chloroform)
As the paragraph descriping shows that 59801-62-6 is playing an increasingly important role.
