Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 27006-76-4, name is 5-Chloro-1,3-dimethyl-1H-pyrazole-4-carboxaldehyde, This compound has unique chemical properties. The synthetic route is as follows., name: 5-Chloro-1,3-dimethyl-1H-pyrazole-4-carboxaldehyde
General procedure: To a well stirred solution of substituted phenol (30 mmol) in DMF or DMSO (30 mL), KOH wasadded (40 mmol) at room temperature. The resulting mixture was heated to 40 C for 2-4 h, and thencompound 1 (20 mmol) was added thereto. The reaction solution was heated to 105 C for 8-24 h.After being cooled to room temperature, the mixture was poured into water and extracted with ethylacetate (3 50 mL). The combined extracts were dried over anhydrous magnesium sulfate, filtered,and evaporated to afford intermediate 2, with yields ranging from 52% to 76% [25].
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 27006-76-4.
