Versuchsvorschrift

A solution of 1-((3-((((3aR,4R,6R,6aR)-6-(6-amino-9H-purin-9-yl)-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl)methyl)(methyl)amino)cyclobutyl)methyl)-3-(4-(tert-butyl)phenyl)urea (55 mg) in HCl/MeOH (2.5 mol/L) (2 mL) was stirred at RT for 2 h and then concentrated to dryness. K2CO3 (52 mg) in water (0.5 mL) and MeOH (5 mL) was added. The resulting mixture was stirred for another 10 min at RT, filtered and the filtrate was concentrated. The residue was purified by preparative-HPLC to give Compound 110 (10 mg, yield: 25%) as a white solid. 1HNMR (500 MHz, MeOD): δH 8.26 (s, 1H), 8.18 (s, 1H), 7.26-7.19 (m, 4H), 5.96 (d, J=4.5 Hz, 1H), 4.674-4.655 (m, 1H), 4.24-4.16 (m, 2H), 3.15 (d, J=5.0 Hz, 2H), 2.83-2.73 (m, 3H), 2.20-1.59 (m, 8H), 1.26 (s, 9H) ppm; ESI-MS (m/z): 539.3 [M+1]+.
