実験手順

A mixture of tert-butyl 4-[7-amino-1-(3-methoxy-4-nitrophenyl)-1H-pyrazolo[4,3-d]pyrimidin-3-yl]-1,2,3,6-tetrahydro-1-pyridinecarboxylate (200 mg, 0.428 mmol) and 10% palladium on carbon (100 mg) in methanol (20 mL) and hydrogenated in a Parr shaker at 55 psi for 18 hours. The catalyst was removed by filtration through a pad of diatomaceous earth and the filtrate concentrated under reduced pressure then the residue was dissolved methanol (20 mL). Platinum (IV) oxide (100 mg) was added and the mixture was hydrogenated in a Parr shaker at 55 psi for 30 hours. The catalyst was removed by filtration through a pad of diatomaceous earth and the filtrate concentrated under reduced pressure to provide the title compound as a brown solid (175 mg, 93%): 1H NMR (DMSO-d6, 400 MHz) δ 8.22 (s, 1H), 6.96 (d, 1H), 6.84 (d, 1H), 6.74 (d, 1H), 6.5 (bs, 2H), 5.75 (bs, 2H), 4.03 (m, 2H), 3.76 (s, 3H), 3.22 (m, 1H), 2.93 (m, 2H), 1.7-2.1 (m, 4H), 1.42 (s, 9H) RP-HPLC (Hypersil HS C18, 5 μm, 100 A, 250×4.6 mm; 5%-100% acetonitrile-0.05 M ammonium acetate over 25 min, 1 mL/min) tr 16.93 min; MS: MH+ 440.2
