Electric Literature of 355806-00-7, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 355806-00-7, name is (3R,5S,6E)-7-[4-(4-Fluorophenyl)-6-isopropyl-2-[(methanesulfonyl) methylamino]pyrimidin-5-yl]-3,5-dihydroxyhept-6-enoic acid tert-butyl ester, molecular formula is C26H36FN3O6S, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
B . 7- [4-(4-fluorophenyl)-6-isopropyl-2-(methanesulfonyl-methyl- amino)-pyrimidin-5-yl]- (3i?,5S)-dihydroxy-hept-6-enoic acid zinc salt (2:1)7.81 g (14.5 mmol) of 7-[4-(4-fluorophenyl)-6-isopropyl-2- (methanesulfonyl-methyl-amino)-pyrimidin-5-yl]-(3i?,5S)-dihydroxy- hept-6-enoic acid fert-butylester are dissolved in 200 ml of ethanol at room temperature and 58 ml of 0.25 M sodium hydroxide solution (14.5 mmol) are added dropwise in 30 minutes. The reaction mixture is kept at the temperature of 60 C for 4 hours. Subsequently the solution is filtered on a G4 sintered glass filter and the ethanol is evaporated at 20 Hgmm pressure. The residue is mixed with 40 ml of water and extracted three times with 15 ml of ethylacetate each and the aqueous layer is evaporated. From the residue, 10 ml of ethanol is evaporated twice and the remaining solids are stirred in 40 ml of diisopropylether and filtered. Yield, 6.65 g (91 %)The quality of the product is identical in all respects with those of the product obtained in Example 5.
According to the analysis of related databases, 355806-00-7, the application of this compound in the production field has become more and more popular.
