実験手順

To a solution of 7-amino-10a-(4-methoxyphenyl)-1-[(3-methyl-1,2-oxazol-4-yl)carbonyl]-2,3,10,10a-tetrahydro-1H,5H-imidazo[1,2-a]pyrrolo[1,2-d]pyrazin-5-one (33 mg, 0.081 mmol) in CH2Cl2 (0.5 mL) was added cyclohexanone (9 μL, 0.081 mmol), acetic acid (7 μL, 0.12 mmol) followed by sodium triacetoxyborohydride (26 mg, 0.12 mmol). After stirring the mixture for three further hours, cyclohexanone (20 μL, 0.18 mmol) was added followed by the addition of additional acetic acid (20 μL, 0.34 mmol). The mixture was quenched with a saturated aqueous solution of NaHCO3. Additional CH2Cl2 (3 mL) was added and the organic layer separated, the aqueous layer was further extracted with CH2Cl2 (3 mL). The organic layers were combined dried (Na2SO4), filtrated, concentrated in vacuo to give a residue that was purified by flash chromatography (Biotage SP4, gradient 0-10% MeOH in EtOAc) and reverse phase chromatography (Biotage SP4, 12 g C18 cartridge; gradient ACN in water). The compound 7-(cyclohexylamino)-10a-(4-methoxyphenyl)-1-[(3-methyl-1,2-oxazol-4-yl)carbonyl]-2,3,10,10a-tetrahydro-1H,5H-imidazo[1,2-a]pyrrolo[1,2-d]pyrazin-5-one (112) was isolated as a solid (1.6 mg, yield 1%).
