Examples
Embodiment 1
[0068] Example 1: Ethyl 3-(ethoxy(phenyl)methyl)indazine-1-carboxylate (yield 80%)
[0069]
[0070] Add ethyl 2-pyridinecarboxylate (0.30mmol), phenylpropynaldehyde (0.30mmol), EtOH (3.0mmol), PivOH (0.20eq.), 150mg 5A molecular sieves successively in a 25ml schlenk tube, and then pass into Ar, Reaction at room temperature for 2h. After the reaction was detected by TLC, it was extracted with ethyl carboxylate (10 mL×3), the organic layers were combined and washed with saturated brine, and then washed with anhydrous MgSO 4 to dry. The obtained organic phase was distilled off under reduced pressure to remove most of the solvent, and the crude product was separated and purified by column chromatography to obtain a pure sample. The structure of the product 1 H NMR, 13 C NMR, GC-MS, HRMS and IR for analysis and confirmation.
