실험 절차

In a similar manner to Step 1 of Example 20, Compound 158 (20.0 mg, 0.0587 mmol) was dissolved in DMF (1 mL), and the solution was treated with EDCI (23 mg, 0.12 mmol), HOBT monohydrate (7.9 mg, 0.059 mmol) and 1-(2-hydroxyethyl)piperazine (31 mg, 0.24 mmol). The mixture was added with water and ethyl acetate, and then extracted with 1 mol/L hydrochloric acid. The aqueous layer was added with sodium carbonate to adjust the pH to 9 and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was dissolved in chloroform, and the solution was added with hexane and stirred for 30 minutes. The solid was collected by filtration, washed with hexane and dried under reduced pressure to obtain Compound 160 (16.6 mg, yield 62%).
