Versuchsvorschrift

To a solution of isoindoline (238 mg, 2.0 mmol) in dry 1,4-dioxane (10 mL) was added 4-chloro-2-methylphenyl isocyanate (335 mg, 2.0 mmol) under argon at room temperature. The reaction mixture was then stirred at RT overnight. The solvent was evaporated under reduced pressure, and the residue was purified by recrystallization from ethanol to give the title compound (540 mg, 94%) as a white solid. 1H NMR (500 MHz, DMSO-d6): δ 2.24 (s, 2H), 4.76 (s, 4H), 7.20 (dd, J=2.5, 8.5 Hz, 1H), 7.27 (d, J=2.5 Hz, 1H), 7.30-7.32 (m, 2H), 7.34-7.37 (m, 2H), 7.42 (d, J=8.5 Hz, 1H), 7.84 (s, 1H); 13C NMR (DMSO-d6): δ 17.7, 51.9, 122.8, 125.6, 126.8, 127.3, 128.1, 129.5, 134.7, 136.8, 154.2; MS (MH+, 287); EA calc'd for C16H15ClN2O: C, 67.02; H, 5.27; N, 9.77. Found C, 66.82; H, 5.41; N, 9.92.
