Versuchsvorschrift

To a solution of tert-butyl (1S,2R)-2-(5-oxo-4-(m-tolylamino)-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-2-ylamino)cyclohexylcarbamate (50.4 mg, 0.111 mmol) in HOAc (2 mL) was added hydrochloric acid (0.5 mL, 16.46 mmol). The mixture was stirred at RT for 30 min and then concentrated under reduced pressure. The residue was treated with saturated aq NaHCO3 and extracted with EtOAc. The organic layers were washed with saturated aq NaHCO3, water, and brine, were dried over anhydrous Na2SO4, and then filtered. The filtrate was concentrated under reduced pressure and the residue was purified by column chromatography (SiO2, EtOAc/MeOH=20/1) to give the title compound as a white powder (11.3 mg, 29%). 1H NMR (400 MHz, CDCl3) δ ppm 1.48-1.80 (m, 10H), 2.37 (s, 3H), 3.24 (br s, 1H), 4.07 (br s, 1H), 4.20 (s, 2H), 5.55 (br s, 1H), 5.89 (br s, 1H), 6.89-6.91 (m, 1H), 7.22-7.24 (m, 1H), 7.53-7.63 (m, 2H), 8.49 (br s, 1H). [M+H] calc'd for C19H25N6O, 353. found, 353.
