A common heterocyclic compound, 1120-82-7, name is (1H-Pyrazol-1-yl)methanol, molecular formula is C4H6N2O, 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. 1120-82-7.
General procedure: To a solution of N-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-3-hydroxybenzamide (12) (0.250g, 0.838mmol) in anhydrous THF (5mL), the corresponding alcohol (0.838mmol) and PPh3 (0.330g, 1.25mmol) were added. The reaction mixture was cooled on ice bath and DIAD (0.25mL, 1.25mmol) was added. The reaction was stirred overnight at room temperature. The solvent was evaporated under reduced pressure and the crude product was purified by flash chromatography.
The synthetic route of (1H-Pyrazol-1-yl)methanol has been constantly updated, and we look forward to future research findings.
