실험 절차

A 20 mL microwave vial was charged with 3-chloroisoquinoline-8-carboxylic acid (1 g, 4.82 mmol) in 5 mL of MeOH and then was added with thionyl chloride (0.703 mL, 9.63 mmol). Stirred at 65° C. overnight and then concentrated in vacuo. Purified by silica gel chromatography (0-50% EtOAc in hexane) yielded Methyl 3-chloroisoquinoline-8-carboxylate (27-1).
