الإجراء التجريبي

A mixture of 5-amino-6-nitroisoindoline-1,3-dione (2.27 g, 10.98 mmol), (R)-3-aminopropane-1,2-diol (1.0 g, 10.98 mmol), and imidazole (0.75 g, 10.98 mmol) in 100 mL of pentanol was heated to reflux and maintained for 8 h and allowed to cool down to rt. The precipitate was filtered and washed with heptanes and dried to give a yellow crystalline solid (2.57 g, 9.14 mmol, 83%). 1H NMR (500 MHz, DMSO-d6) δ 8.38 (s, 2H), 8.31 (s, 1H), 7.45 (1, 1H), 4.90 (d, J=5.0 Hz, 1H), 4.66 (t, J=5.5 Hz, 1H), 3.82-3.74 (m, 1H), 3.55 (d, J=6.5 Hz, 2H), 3.42-3.18 (m, 2H). ESI MS: m/z 279.8 (M−1).
