Mode opératoire

10a-(4-methoxyphenyl)-1-[(3-methyl-1,2-oxazol-4-yl)carbonyl]-7-[4-(trimethylsilyl)-1H-1,2,3-triazol-1-yl]-2,3,10,10a-tetrahydro-1H,5H-imidazo[1,2-a]pyrrolo[1,2-d]pyrazin-5-one (10.6 mg, 0.012 mmol) was dissolved in a mixture of acetic acid/water/THF (3:1:1; 1 mL). The mixture was stirred at 60° C. When the reaction was complete (48 hours; monitored by LCMS) water was added followed by a saturated aqueous solution of NaHCO3. The mixture was then extracted with EtOAc (3 times) and the organics washed with brine, dried (Na2SO4), filtrated and concentrated in vacuo. The resulting material was purified by flash chromatography (Silica gel, EtOAc/Hex 3:1 followed by 100% EtOAc) to give compound 10a-(4-methoxyphenyl)-1-[(3-methyl-1,2-oxazol-4-yl)carbonyl]-7-(1H-1,2,3-triazol-1-yl)-2,3,10,10a-tetrahydro-1H,5H-imidazo[1,2-a]pyrrolo[1,2-d]pyrazin-5-one (113) as a white solid (2.28 mg, yield 25%)
