Reaction Steps

A solution of (9H-fluoren-9-yl)methyl 5-(7-chloropyrido[4,3-b]pyrazin-5-yl)hexahydropyrrolo[3,4-b]pyrrole-1 (2H)-carboxylate (140 mg) and piperidine (2 mL) in CH2Cl2 (8 mL) was stirred at room temperature for 3 hours. The volatiles were removed under reduced pressure. The residue was treated with EtOAc/H2O, separated, and the aqueous solution was extracted with EtOAc. The combined extracts were washed with brine, dried over Na2SO4, filtered, and concentrated. The residue was purified by chromatography to afford the title compound. MS (m/z): 276 (M+H)+.
