실험 절차

A mixture of ethyl N-[(1-cyclohexyl-6-hydroxy-2,4-dioxo-1,2,3,4-tetrahydro-5-pyrimidinyl)carbonyl]glycinate (340 mg, 1.0 mmoles), pulv. Potassium carbonate (740 mg, 5.35 mmoles) and 6-(bromomethyl)-1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene (250 mg, 0.89 mmoles) in dimethylformamide (5 mL) was vigorously stirred at 100° C. for 3 hours. The mixture was poured into 1 molar hydrochloric acid and extracted with ethyl acetate. The organic solution was washed with 1 molar hydrochloric acid and evaporated. The residue was purified by flash chromatography (10-50% ethyl acetate in hexane), the required fractions evaporated, dissolved in ethanol (5 mL) and 1 molar sodium hydroxide solution (1.0 mL) and 6 molar sodium hydroxide solution (1.0 mL) added. The mixture was stirred overnight, acidified and extracted with ethyl acetate (×2), the combined extracts washed with 1 molar hydrochloric acid, dried and evaporated to give the title compound (156 mg, 35%). 1H NMR (400 MHz, DMSO-d6) δ ppm 13.07 (br. s., 1 H), 7.24 (dd, J=4.80, 3.28 Hz, 2 H), 6.98 (dd, J=8.21, 1.39 Hz, 1 H), 4.93 (s, 2 H), 4.66 (t, J=11.87 Hz, 1 H), 4.13 (d, J=5.56 Hz, 2 H), 2.19-2.36 (m, 2 H), 1.79 (d, J=12.63 Hz, 2 H), 1.62 (s, 7 H), 1.01-1.37 (m, 15 H).
