実験手順
A mixture of 4,6-dichloro-2,5-diformamidopyrimidine (5.4 g, 23.0 mmol), 3-benzyloxyprop-1-oxyamine (4.14, 23.0 mmol), triethylamine (10 ml) and dioxan (50 ml) was stirred at reflux temperature for 3 hours, cooled, filtered and evaporated to dryness. Column chromatography on silica gel (eluted with chloroform-ethanol, 25:1) gave the title compound (4.38 g, 50%). IR: υmax (KBr) 3248, 1692, 1589, 1570, 1473, 1420 cm-1. 1H NMR: δH [(CD3)2SO] 1.88 (2H, quintet, J=6.3 Hz, CH2CH2CH2) 3.57 (2H, t, J=6.3 Hz, CH2OCH2Ph), 3.95 (2H, t, 6.3 Hz, CH2ONH), 4.47 (2H, s, CH2Ph), 7.32 (5H, m, Ph), 8.14 (1H, s, CHONH), 9.26 (1H, s, CHONH), 9.42 (1H, br.s, D2O exchangeable, NHOCH2), 10.83 (2H, br.s, 2×NHCHO).
