The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 314021-93-7, name is 1-Methyl-1H-pyrazolo[4,3-d]pyrimidin-7-ol. This compound has unique chemical properties. The synthetic route is as follows. Application In Synthesis of 1-Methyl-1H-pyrazolo[4,3-d]pyrimidin-7-ol
Compound 9: To a solution of 8 (0.835 g, 5.5 mmol) in 10 mL thionyl chloride was added 0.5 mL DMF. The resulting mixture was heated to 90 C. under nitrogen for 1 hour. After cooling to room temperature, the solvents were removed under reduced pressure. Water was added to the resulting residue and the mixture was extracted with dichloromethane (×3). The combined organics were dried (MgSO4) and concentrated under reduced pressure to afford 9 (0.94 g, 100%), ES (+) MS m/e=169 (M+1).
With the rapid development of chemical substances, we look forward to future research findings about 314021-93-7.
