The mixture was stirred for 30 min at 0 C. Next vinamidinium salt 2 (0.48 mmol) was added and the resulting mixture heated at 80 C for 6 h and the residue partitioned between CH2Cl2 and H2O. The aqueous layer was extracted with CH2Cl2 and the combined organic layers dried over Na2SO4, filtered and the solvents removed in vacuo. The crude residue was purified by column chromatography (10% EtOAc in hexane) to give products 3a-e. For pyrazolo[3,4-b]pyridine 3f, after evaporation of the solvent, THF (6 mL) and 1 N HCl (6 mL) were added. The mixture was allowed to stir at room temperature for 2 h, then neutralized with saturated aqueous NaHCO3 and extracted with CH2Cl2 (3 \u00d7 15 mL). Work-up and purification as above gave 3f.<\/p>\n<p>The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking.
