반응 단계
Compound 6 (480 mg) was dissolved in toluene (100 mL), and N,N-diethylglycin sodium salt (296 mg) and p-toluenesulfonic acid monohydrate (490 mg) were added to the solution, followed by stirring under reflux for 5 hours. The solvent was evaporated to dryness, and the residue was purified by silica gel column chromatography (CHCl3-MeOH), to thereby yield the target product (yield: 237 mg, 37.7%).
