Versuchsvorschrift

A mixture of 6-bromo-9H-purine (1.65 g, 0.008270 mol), 2-(1-aminopropyl)-3-iodo-6-methyl-4H-pyrido[1,2-a]pyrimidin-4-one (2.58 g, 0.00752 mol), and N,N-diisopropylethylamine (1.571 mL, 0.009022 mol) in ethanol (60 mL) was refluxed under nitrogen overnight. The mixture was concentrated and the resulting residue was purified on silica gel, eluting with 0 to 10% methanol in methylene chloride, to provide the desired product (2.86 g, 82.5%). LCMS calculated for C17H17IN7O (M+H)+: m/z=462.1. Found: 462.2. 1H NMR (DMSO-d6, 300 MHz) δ 8.31 (2H, m), 8.19 (1H, s), 8.15 (1H, s), 7.69 (1H, dd, J=8.7 and 6.9 Hz), 7.44 (1H, d, J=8.7 Hz), 6.99 (1H, d, J=6.9 Hz), 5.69 (1H, m), 2.89 (3H, s), 1.91 (2H, m), 0.95 (3H, t, J=7.2 Hz) ppm.
