실험 절차

Dioxane HCl (4 mL) was added to 3,3-dimethyl-5-[3-(4-methyl-pyridin-3-yl)-2-oxo-imidazolidin-1-yl]-1-(2-trimethylsilanyl-ethoxymethyl)-1,3-dihydro-indol-2-one (I-147a: 50 mg) and the resulting mixture was stirred room temperature for 1 hour. The reaction was monitored by TLC (10% MeOH in CHCl3). The reaction mixture was basified with bicarbonate solution and extracted with DCM. The organic layer was concentrated; the concentrate was recrystallized with DCM and hexane and dried to afford 37 mg of the product (94.87% yield).
