Versuchsvorschrift

To a solution of 1-phenylimidazolidin-2-one (211) (100 mg, 0.62 mmol) [P. Mayer, P. Brunel, C. Chaplain, C. Piedecoq, F. Calmel, P. Schambel, P. Chopin, T. Wurch, P. J. Pauwels, M. Marien, J.-L. Vidaluc, T. Imbert J. Med. Chem. 2000, 43, 3653-3664; W. Su, Y. Zhang J. Chem. Res. Synop. 2000, 9, 440-441] in THF (6 mL) was added triphosgene (189 mg, 0.62 mmol) and the solution was stirred for 3 hrs at 60° C. The reaction mixture was cooled to RT before the addition of aniline 15 (229 mg, 0.65 mmol) and DIPEA (648 μL, 3.72 mmol) and stirring was continued for an hour. The reaction mixture was concentrated and partitioned between EtOAc and water. A precipitate was formed which was collected by filtration. The organic layer was separated, dried and concentrated. The residue was combined with the collected precipitate, dry loaded to a column and eluted with EtOAc/MeOH (9:1), to produce title compound 210 (150 mg, 43% yield) as an off-white solid. 1H NMR (DMSO-d6) δ (ppm): 10.57 (s, 1H), 8.42 (d, J=5.5 Hz, 1H), 7.95 (d, J=1.1 Hz, 1H), 7.83 (dd, J=2.5 and 13.3 Hz, 2H), 7.77 (d, J=1.2 Hz, 1H), 7.66 (s, 1H), 7.61 (dd, J=1.0 and 8.8 Hz, 1H), 7.49-7.41 (m, 4H), 7.16 (t, J=7.2 Hz, 1H), 6.57 (d, J=5.5 Hz, 1H), 4.03 (q, 2H), 4.04-3.92 (m, 4H), 1.38 (t, 3H). MS (m/z): 543.0 (M+H).
