3-aminoisoindol-1-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 3-Aminoisoindol-1-one (0.292 g, 2.00 mmol) and 6-piperazin-1-ylpyridazine-3-carboxylic acid (2-cyclopropylethyl)amide (0.825 g, 3.00 mmol) were boiled together in ethanol (20 mL) for 48 hours. The solution was concentrated in vacuo. This residue was purified by column chromatography. The title compound was obtained as a white solid in 40% yield (0.328 g). 1H NMR (300 MHz, CDCl3) δ 8.07 (d, J=9.5 Hz, 1H), 7.97 (t, J=5.8 Hz, 1H), 7.76 (d, J=7.0 Hz, 1H), 7.64 (d, J=7.3 Hz, 1H), 7.52 (m, 1H), 7.01 (d, J=9.5 Hz, 1H), 4.42-4.35 (m, 4H), 4.23-4.20 (m, 2H), 3.93-3.89 (m, 2H), 3.54 (dd, J=6.7 and 13.2 Hz, 1H), 1.49 (m, 1H), 0.79-0.66 (m, 1H), 0.47-0.41 (m, 2H), 0.10-0.05 (m, 2H). 13C NMR (75 MHz, CDCl3) δ 181.5, 174.6, 162.9, 159.6, 145.6, 138.1, 134.9, 132.5, 131.7, 127.3, 124.0 123.3, 112.2, 47.2, 46.4 44.5, 43.2, 39.7, 34.5, 8.7, 4.2.
