Procedure

9-(3-Aminopropyl)-8-(6-(dimethylamino)benzo[d][1,3]dioxol-5-ylthio)-9H-purin-6-amine (60 mg, 0.155 mmol), triethylamine (17 mg, 24 μL, 0.170 mmol), cyclopropane carbonyl chloride (16 mg, 14 μL, 0.155 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-28 (66 mg, 93%). 1H NMR (600 MHz, CDCl3): δ 8.33 (s, 1H), 7.40 (t, J=6.1 Hz, 1H), 6.77 (s, 1H), 6.52 (s, 1H), 6.40 (br s, 2H), 5.90 (s, 2H), 4.29 (t, J=6.2 Hz, 2H), 3.11 (q, J=6.0 Hz, 2H), 2.68 (s, 6H), 1.87-1.91 (m, 2H), 1.45-1.49 (m, 1H), 0.98-0.96 (m, 2H), 0.77-0.74 (m, 2H); 13C NMR (150 MHz, CDCl3): δ 173.7, 154.9, 153.0, 151.8, 148.3, 147.5, 146.6, 144.7, 119.9, 119.5, 109.6, 102.5, 101.7, 45.3, 40.6, 35.3, 29.1, 14.9, 7.1 HRMS (ESI) m/z [M+H]+ calcd. for C21H26N7O3S, 456.1818. found 456.1812.
