Synthetic Route of 10070-92-5, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 10070-92-5, name is Pyrimidine-5-carbaldehyde. A new synthetic method of this compound is introduced below.
A mixture of the product from Preparative Example 28 (1.16 g, 4.00 mmol), pyrimidine-5-carboxaldehyde (540 mg, 5.00 mmol), and Ti(OiPr)4 (4.54 g, 16.0 mmol) in anhydrous THF (20 mL) was stirred under N2 at 50 C. for 3 hr. The mixture was cooled to 25 C., NaBH3CN (1.26 g, 20.0 mmol) was added, and the mixture was stirred at 25 C. for 30 min. The mixture was poured into 5% aqueous NaOH (500 mL), saturated aqueous NaCl (50 mL) was added, and the mixture was extracted with CH2Cl2 (3¡Á100 mL). The combined extracts were dried over Na2SO4, filtered, and the solvent was evaporated. The residue was purified by column chromatography on silica gel with CH2Cl2/MeOH/conc. aqueous NH4OH (20:1:0.1). Pale yellow solid (410 mg, 27%) was obtained. M. P. 201-203 C., LCMS: MH+=383.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,10070-92-5, Pyrimidine-5-carbaldehyde, and friends who are interested can also refer to it.
