Reaction Steps

To a solution of (±)-4′-chloro-5-nitro-1,3-dihydrospiro[indene-2,5′-pyrrolo[2,3-d]pyrimidin]-6′(7′H)-one (40 mg, 0.126 mmol, described in Intermediate 4) in EtOAc (10 mL) was added triethylamine (0.026 mL, 0.189 mmol). The mixture was hydrogenated at 30 psi hydrogen over 10% Pd/C (10 mg). After 2 h, the reaction mixture was filtered through a pad of Celite and concentrated in vacuo. The residue was purified by HPLC using a reversed phase C18 column and eluting with a gradient of H2O:CH3CN:CF3CO2H—90:10:0.1 to 5:95:0.1. Lyophilization provided the title compound. MS: m/z=287 (M+1).
