To a solution of 9-(3-aminopropyl)-2-fluoro-8-((6-iodobenzo[d][1,3]dioxol-5-yl)methyl)-9H-purin-6-amine (100 mg, 0.21 mmol) in DMF (3 mL) was added cyclopropanesulfonyl chloride (89 mg, 0.32 mmol) and triethylamine (90 uL, 0.96 mmol). The resulting mixture was stirred at room temperature overnight. The reaction mixture was condensed and purified by flash chromatography to yield WS72 as a white solid (82 mg, 67%). 1H NMR (600 MHz, CDCl3/MeOH-d4): δ 7.32 (s, 1H), 6.79 (s, 1H), 6.02 (s, 2H), 4.27 (s, 2H), 4.22 (t, J=7.3 Hz, 2H), 3.18 (t, J=6.4 Hz, 2H), 2.45-2.50 (m, 1H), 2.00-2.06 (m, 2H), 1.12-1.17 (m, 2H), 0.99-1.04 (m, 2H); 13C NMR (150 MHz, CDCl3/MeOH-d4): δ 159.0 (d, J=209.8 Hz), 156.9 (d, J=19.7 Hz), 152.4 (d, J=18.5 Hz), 151.2 (d, J=2.3 Hz), 149.3, 148.4, 131.4, 119.0, 116.3 (d, J=3.6 Hz), 110.4, 102.4, 88.7, 40.7, 40.1, 39.3, 30.2, 29.9, 5.3; HRMS (ESI) m/z [M+H]+ calcd, for C19H21FIN6O4S, 575.0374. found 575.0390.
