実験手順
A mixture of ethyl N-{[6-hydroxy-2,4-dioxo-3-(phenylmethyl)-1,2,3,4-tetrahydro-5-pyrimidinyl]carbonyl}glycinate (example 11a, 356 mg, 1.03 mmoles), 4-trifluoromethylbenzyl bromide (175 uL, 1.13 mmoles) and sodium carbonate (330 mg, 3.1 mmoles) in dimethylformamide (6.0 mL) was stirred under argon at 100° C. for 2.5 hours. The mixture was cooled, poured into 1 molar hydrochloric acid and extracted with ethyl acetate (×2). The ester was hydrolysed by stirring in a mixture of ethanol (3 mL) and 1 molar sodium hydroxide solution (3 mL) for 3 hours. The mixture was acidified and extracted with ethyl acetate. Purification by preparative HPLC (acetonitrile-water—0.1% TFA, 20-100%) and crystallization from ethanol-water gave the title compound (150 mg, 30%). 1H NMR (400 MHz, DMSO-d6) δ ppm 13.12 (s, 1 H), 10.12 (t, J=5.56 Hz, 1 H), 7.69 (d, J=8.08 Hz, 2 H), 7.53 (d, J=8.08 Hz, 2 H), 7.24-7.35 (m, 5 H), 5.11 (s, 2 H), 5.03 (s, 2 H), 4.14 (d, J=5.81 Hz, 2 H).
