Reference of 799842-07-2, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 799842-07-2 as follows.
General procedure: Aq 1 M NaOH (9 mL, 1.5 equiv) was added to a stirred MeOH (20mL) solution of the appropriate aromatic thiol (7.2 mmol, 1.2equiv). The solution was stirred at r.t. for 15 min and then the heterocyclicalkyl bromide 2 or 3 (6 mmol, 1 equiv) was added. When rosuvastatin moiety bromides 2 were used, THF (10 mL) was also added to the mixture to improve solubility. After 18 h, the solvent was evaporated, the residue was dissolved in CH2Cl2 (50 mL), and washed with H2O (100 mL). The aqueous phase was additionally extracted with CH2Cl2 (2 ¡Á 25 mL). The combined organic phases were dried (MgSO4) and the solvent was evaporated. The residuewas recrystallized and the isolated product was dried in vacuumovernight at 60 C below 50 mbar to give the pure sulfide heterocyclic precursor 4 or 5 in 75-97% yield.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,799842-07-2, its application will become more common.
