Benzyl 3-(3-((((3aR,4R,6R,6aR)-6-(4-((2,4-dimethoxybenzyl)amino)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl)methyl)amino)cyclobutyl)propanoate (2.3 g, 3.43 mmol) was mixed with K2CO3 (3.3 g, 24 mmol) and 2-iodopropane (5.8 g, 34.3 mmol) in MeCN (25 mL) in a sealed tube, then heated to 95° C. with stirring for 20 h. The reaction mixture was filtered and rinsed with MeCN (30 mL), the filtrate was evaporated in vacuo to afford the desired compound (2.1 g, yield: 88%) as a white solid, which was used for next step without further purification. 1H NMR (500 MHz, MeOD): δH 8.13 (s, 1H), 7.35-7.29 (m, 5H), 7.18 (d, J=3.0 Hz, 1H), 7.13 (d, J=8.5 Hz, 1H), 6.64 (d, J=3.0 Hz, 1H), 6.53 (d, J=2.5 Hz, 1H), 6.41 (dd, J=8.5 and 2.5 Hz, 1H), 6.18 (d, J=2.5 Hz, 1H), 5.33-5.32 (m, 1H), 5.08-5.06 (m, 2H), 4.90-4.89 (m, 1H), 4.64 (s, 2H), 4.15-4.14 (m, 1H), 3.83 (s, 3H), 3.75 (s, 3H), 3.37-3.36 (m, 0.43H), 3.01-2.98 (m, 0.59H), 2.92-2.88 (m, 1H), 2.70-2.40 (m, 3H), 2.24-2.18 (m, 2H), 2.10-1.80 (m, 3H), 1.75-1.69 (m, 2H), 1.61-1.52 (m, 5H), 1.38 (s, 3H), 0.94 (d, J=6.5 Hz, 3H), 0.81-0.79 (m, 3H) ppm; LC-MS (m/z): 714.0 [M+1]+.
