Versuchsvorschrift

N-[(6-hydroxy-1,3-bis{[2-(methyloxy)phenyl]methyl}-2,4-dioxo-1,2,34-tetrahydro-5-pyrimidinyl)carbonyl]glycine. A mixture of 1,3-bis{[2-(methyloxy)phenyl]methyl}-2,4,6(1H,3H,5H)-pyrimidinetrione (1.64 g, 4.45 mmoles) and diisopropylethylamine (1.56 mL, 8.94 mmoles) was stirred in dichloromethane (30 mL) and treated with ethyl isocyanatoacetate (500 uL, 4.45 mmoles). The mixture was stirred for 5 hours, washed with 1 molar hydrochloric acid (×2), evaporated, taken up in ethanol-6 molar sodium hydroxide and stirred overnight. The mixture was acidified and extracted into ethyl acetate (×2). The extracts were washed with 1 molar hydrochloric acid evaporated, dried and evaporated. The title compound was recrystallized from acetic acid (1.0 g, 48%). 1H NMR (400 MHz, DMSO-d6) δ ppm 12.51 (br. s., 1 H), 10.11 (t, J=4.93 Hz, 1 H), 7.20-7.28 (m, 2 H), 7.00 (d, J=7.83 Hz, 2 H), 6.86-6.96 (m, 4 H), 5.00 (s, 4 H), 4.10-4.18 (m, 2 H), 3.82 (s, 6 H).
