Synthetic Route of 35344-95-7<\/a>, A common heterocyclic compound, 35344-95-7, name is 1H-Pyrazole-4-carbaldehyde, molecular formula is C4H4N2O, 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.<\/p>\n

To a solution of li\/-pyrazole-4-carbaldehyde (300 mg, 3.12 mmol) was added ethyl 2-(triphenylphosphoranylidene)acetate (1360 mg, 3.90 mmol) in toluene (10 mL). The mixture was heated at 90 \u00b0C for 2 h. The solvent was removed in vacuo. The crude material was purified by flash chromatography to afford Example 7A (450 mg, 2.71 mmol, 87percent yield) as a white solid. LCMS (ES): m\/z 167.1 [M+H]+.<\/p>\n

The synthetic route of 35344-95-7 has been constantly updated, and we look forward to future research findings.<\/p>\n
