실험 절차

To a solution of (6S,7aR)-6-Hydroxy-2-[4-(2,2,2-trifluoro-ethoxy)-phenyl]-hexahydro-pyrrolo[1,2-c]imidazol-3-one (100 mg, 0.316 mmol) in THF (3 mL) was added NaH (60% dispersion, 18.96 mg, 0.474 mmol) at room temperature and stirred for 30 min and then added 1-Bromo-3-methyl-butane (57.3 mg, 0.379 mmol) and left stirring for 12 h. The reaction mixture was quenched with NH4Cl aq., DCM was added. The organic layer was separated, washed with water and brine, dried over Na2SO4 and concentrated. The residue was purified through column chromatography (elution with ethyl acetate in hexane) to afford 60 mg (49%) of the title compound. LC-MS: 386 [M+1]+.
