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), pivaloyl chloride (19 mg, 19 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-29 (65 mg, 89%). 1H NMR (600 MHz, CDCl3): δ 8.30 (s, 1H), 7.65 (t, J=6.2 Hz, 1H), 6.77 (s, 1H), 6.50 (s, 1H), 6.39 (br s, 2H), 5.90 (s, 2H), 4.26 (t, J=6.0 Hz, 2H), 3.04 (q, J=6.0 Hz, 2H), 2.68 (s, 6H), 1.83-1.87 (m, 2H), 1.27 (s, 9H); 13C NMR (150 MHz, CDCl3): δ 178.8, 154.9, 152.9, 151.9, 148.3, 147.5, 146.6, 144.7, 119.8, 119.7, 109.5, 102.5, 101.7, 45.3, 40.3, 38.8, 34.8, 28.9, 27.7; (ESI) m/z [M+H]+ calcd. for C22H30N7O3S, 472.2131. found 472.2128.
