288-13-1, These common heterocyclic compound, 288-13-1, name is 1H-Pyrazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Reference Production Example 1-1 1H-pyrazole-1-ylmethanol The mixture of 2.04 g of pyrazole, 2.00 g of paraformaldehyde and 1 ml of triethylamine was stirred at 130 C for 10 hours. After the reaction mixture was cooled to room temperature, acetone was added to the reaction mixture, and then the mixture was filtered. The filterate was concentrated under reduced pressure. Hexane was added to the residue, and then crystalline was formed. The crystalline was collected to obtain 3.10 g of 1H-pyrazole-1-ylmethanol. 1H-NMR(CDCl3,TMS,delta(ppm)):5.51(2H,s),6.30(1H,t),7.58-7.61(2H, m)
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 288-13-1.
