실험 절차

(S)-4-(2-(3-(4-(N-(tert-butoxycarbonyl)methylsulfonamido)-3-(cyclopropylmethoxy)benzyloxy)-3-oxopropanoyloxy)-2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)ethyl)-3,5-dichloropyridine 1-oxide (70 mg, 0.08 mmol) was dissolved in DCM (1 ml), and HCl 4M in Dioxane (500 μM) was added. The mixture was stirred at RT for 3 hours. The reaction was quenched with water, and the product was extracted with EtOAc. The organic phase was dried over Na2SO4 and evaporated to dryness. The crude was purified by Preparative reverse-phase HPLC to yield 10 mg of the final product (Yield: 16%).
