실험 절차

To a solution of tert-butyl {3-[(3-aminobenzoyl)amino]phenyl}carbamate (0.500 g, 1.53 mol) and 2,4,5-trichloropyrimidine (0.25 g, 1.4 mmol) in DMF (3.7 mL) was added potassium carbonate (0.29 g, 2.1 mmol). The resulting mixture was stirred overnight at room temperature. The reaction was quenched with saturated (sat'd) NH4Cl and water. EtOAc was added and the layers separated. The aqueous layer was extracted with EtOAc twice and the combined organics were washed with water, dried, filtered and concentrated to give 800 mg of crude product, which was purified by Combi-Flash column chromatography (12 g column, 0 to 30% EtOAc in hexane) to give the desired product (66 mg, 10%). LCMS for C22H21Cl2N5O3 (M-tBu+H)+: m/z=420.0, 418.1. 1H NMR (400 MHz, CD3OD): δ 8.26 (s, 1H), 8.11 (t, J=2.0 Hz, 1H), 7.89 (ddd, J=8.0, 2.0, 1.2 Hz, 1H), 7.85 (t, J=2.0 Hz, 1H), 7.74 (ddd, J=7.6, 2.0, 0.8 Hz, 1H), 7.53 (t, J=8.0 Hz, 1H), 7.32 (dd, J=8.0, 1.2 Hz, 1H), 7.24 (t, J=8.0 Hz, 1H), 7.19 (m, 1H), 1.52 (s, 9H).
