N-{[6-Hydroxy-2,4-dioxo-1-phenyl-3-(phenylmethyl)-1,2,3,4-tetrahydro-5-pyrimidinyl]carbonyl}glycine. A mixture of ethyl 6-hydroxy-1-(2-nitrophenyl)-2,4-dioxo-3-(phenylmethyl)-1,2,3,4-tetrahydro-5-pyrimidinecarboxylate (59 mg, 0.14 mmoles), DBU (80 mg, 0.52 mmoles) and glycine (40 mg, 0.53 mmoles) in ethanol (3 mL) was sealed in a flask and heated in a microwave reactor at 170° C. for 1 hour. The reaction mixture was poured into 1 molar hydrochloric acid and extracted with dichloromethane (×2) and washed with 1 molar hydrochloric acid. The title compound was obtained by purification by preparative HPLC (10-80% acetonitrile-water-0.1% TFA)(17 mg, 28%) 1H NMR (400 MHz, DMSO-d6) δ ppm 13.14 (br. s., 1 H), 10.04 (br. s., 1 H), 8.25 (dd, J=8.21, 1.14 Hz, 1 H), 7.93 (dt, J=7.71, 1.26 Hz, 1H), 7.71-7.81 (m, 2 H), 5.06 (s, 2 H), 4.14 (d, J=5.56 Hz, 2 H)
