실험 절차

A solution of tert-butyl (2S,6R,8aR)-3-oxo-6-(7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)-octahydroindolizin-2-ylcarbamate 127.4 (550 mg (1.02 mmole) in MeOH (21 mL) was treated with of 4 M HCl in 1,4-dioxane (4.0 mL (20.3 mmol) and stirred at room temperature for 23 hr. The mixture was concentrated to dryness, and the residue was dissolved in MeOH (20 ml) and treated with polymer-supported carbonate resin (1.2 g, 3.5 mmol/g). The suspension was stirred at room temperature for 1 hour. The resin was removed by filtration through a celite plug, and the filtrate was concentrated in vacuo to yield 414 mg of (2S,6R,8aR)-2-amino-6-(7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)hexahydroindolizin-3(5H)-one 127.5 as pale yellow solid that was used without further purification. 1H NMR (400 MHz, CHLOROFORM-d) δ 8.42 (s, 1H), 8.04 (d, J=8.3 Hz, 2H), 7.43 (d, J=4.0 Hz, 1H), 7.28 (d, J=8.8 Hz, 2H), 6.49 (d, J=3.8 Hz, 1H), 5.64-5.46 (m, 1H), 4.41 (br. s., 1H), 4.22 (d, J=14.1 Hz, 1H), 3.72-3.54 (m, 2H), 3.08 (dd, J=3.1, 13.9 Hz, 1H), 2.38 (s, 3H), 2.10 (ddd, 0.1=4.3, 8.7, 13.3 Hz, 1H), 2.04-1.91 (m, 1H), 1.90-1.61 (m, 4H), 1.47 (dd, J=2.9, 11.9 Hz, 1H); LCMS (ESI) m/z: 441.2 [M+H]+.
