Reaction Steps

To a solution of 8-((6-iodobenzo[d][1,3]dioxol-5-yl)thio-9H-purin-6-amine (50 mg, 0.12 mmol) in DMF (2 mL) was added N-(3-bromopropyl)isobutyramide (50 mg, 0.24 mmol) and Cs2CO3 (78 mg, 0.24 mmol). The resulting mixture was stirred at room temperature overnight. The reaction mixture was condensed under vacuum and the residue was purified by Prep TLC (CH2Cl2:NH3-MeOH (7N), 20:1) to yield WS46 as a white solid (22 mg, 34%). 1H NMR (500 MHz, CDCl3/MeOH-d4): δ 8.22 (s, 1H), 7.61 (br s, 1H), 7.41 (s, 1H), 7.08 (s, 1H), 6.07 (s, 2H), 4.27 (m, 2H), 3.21 (m, 2H), 2.45 (s, 1H), 2.02 (m, 2H), 1.19 (d, J=6.9 Hz, 6H); HRMS (ESI) m/z [M+H]+ calcd. for C19H22IN6O3S, 541.0519. found 541.0508.
