実験手順

10a-(4-chlorophenyl)-1-[(3-methyl-1,2-oxazol-4-yl)carbonyl]-5-oxo-2,3,10,10a-tetrahydro-1H,5H-imidazo[1,2-a]pyrrolo[1,2-d]pyrazine-8-carbaldehyde (25 mg, 0.059 mmol) and morpholine (10.2 μL) were combined and stirred at room temperature in 1,2-dichloroethane for 10 min. To the mixture was added sodium triacetoxyborohydride (24.7 mg). After 18 h at room temperature the reaction was quenched by the addition of a saturated aqueous solution of NaHCO3 (1 mL) and CH2Cl2 (5 mL). The organic layers were washed with brine, dried (MgSO4), filtered and evaporated in vacuo to give a yellow solid. The solid was purified by flash column chromatography (Biotage SP4, 4 g cartridge, 0-5% MeOH gradient in CH2Cl2) to give 10a-(4-chlorophenyl)-1-[(3-methyl-1,2-oxazol-4-yl)carbonyl]-8-(morpholin-4-ylmethyl)-2,3,10,10a-tetrahydro-1H,5H-imidazo[1,2-a]pyrrolo[1,2-d]pyrazin-5-one (25) as a white solid (26 mg, yield 89%).
