Reaction Steps

9-(3-Aminopropyl)-8-(6-(dimethylamino)benzo[d][1,3]dioxol-5-ylthio)-9H-purin-6-amine (61 mg, 0.158 mmol), triethylamine (18 mg, 24 μL, 0.174 mmol), cyclopropane sulfonyl chloride (22 mg, 17 μL, 0.158 mmol) in CH2Cl2 (3 mL) was stirred for 2 h at rt. The mixture was dried under reduced pressure and the residue purified by preparatory TLC (CH2Cl2:MeOH—NH3(7N), 20:1) to give MRP-I-31 (55 mg, 71%). 1H NMR (600 MHz, CDCl3): δ 8.30 (s, 1H), 6.78 (s, 1H), 6.66 (t, J=6.8 Hz, 1H), 6.51 (s, 1H), 6.29 (br s, 2H), 5.91 (s, 2H), 4.31 (t, J=6.0 Hz, 2H), 3.02 (q, J=6.1 Hz, 2H), 2.70 (s, 6H), 2.34-2.38 (m, 1H), 1.95-1.99 (m, 2H), 1.15-1.17 (m, 2H), 0.93-0.96 (m, 2H); 13C NMR (150 MHz, CDCl3): δ 154.9, 153.1, 151.7, 148.4, 147.6, 146.3, 144.8, 119.8, 119.4, 109.6, 102.4, 101.8, 45.4, 40.0, 39.0, 30.4, 30.2, 5.26; HRMS (ESI) m/z [M+H]+ calcd. for C20H26N7O4S2, 492.1488. found 492.1468.
