A mixture of 3-(4,5-dihydro-1H-imidazol-2-yl)aniline dihydrochloride monohydrate (stored with 4 A molecular sieves, 48 mg, 0.19 mmol) and 4-ethoxyphenyl isocyanate (33 mg, 0.20 mmol) in dimethylformamide (2 ml) was stirred at room temperature overnight. After removal of the solvent, water (2 ml) was added and the resulting precipitate was collected (18 mg, 64% yield) by filtration. 1H NMR (600 MHz, DMSO-d6) δ 10.5 (br s, 1H), 9.12 (br s, 1H), 8.11 (s, 1H), 7.68 (d, 1H, J=8.4 Hz), 7.52 (t, 1H, 8.4 Hz), 7.47 (d, 1H, J=7.2 Hz), 7.35 (d, 2H, J=7.2 Hz), 6.86 (d, 2H, J=7.2 Hz), 3.98 (s, 4H).
