실험 절차

To a solution of tert-butyl (1-(5-oxo-4-(m-tolylamino)-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-2-yl)piperidin-2-yl)methylcarbamate (207.1 mg, 0.458 mmol) in HOAc (3 mL) was added HCl (1 mL, 32.9 mmol). The mixture was stirred at RT for 1 h and then concentrated under reduced pressure. The residue was treated with saturated aq NaHCO3 (50 mL) and was extracted with EtOAc-THF (1/1, 2×40 mL). The organic layers were washed with saturated aq NaHCO3 (20 mL), water (20 mL), and brine (20 mL), were dried over anhydrous Na2SO4, and then filtered. The filtrate was concentrated under reduced pressure and the residue was washed with EtOH to give the title compound as a pale yellow solid (27.4 mg, 17%). 1H-NMR (DMSO-d6) δ ppm 1.32-1.70 (m, 7H), 1.89-1.92 (m, 1H), 2.31 (s, 3H), 2.74-2.87 (m, 1H), 2.81-2.85 (m, 1H), 2.94 (br s, 1H), 4.17 (s, 2H), 4.68-4.79 (m, 2H), 6.88 (d, 1H, J=7.5 Hz), 7.22-7.25 (m, 1H), 7.49-7.50 (m, 1H), 7.60 (s, 1H), 8.06 (s, 1H), 8.58 (s, 1H). [M+H] calc'd for C19H25N6O, 353; found, 353.5.
