実験手順

Into solutions of 154 (5.0 mmol) in 200 mL of dry toluene were added triethylamine (4 mL) and 2-amino-4,5-methylenedioxy acetophenone (148) (5 mmol). The mixtures were stirred at 20±2° C. for 24 h and then evaporated. The residues were washed with acetone and EtOH and then recrystallized from acetone or EtOH to form 155. Obtained as a pale-yellow solid; mp 144-145° C.; ESI-MS (Positive mode): m/z 324 [M+H]+; 1H-NMR (400 MHz, DMSO-d6): δ 2.63 (3H, s), 6.19 (2H, s), 7.41-7.50 (21-1, m), 7.68 (1H, s), 7.75 (1H, dd, J=1.6, 6.8 Hz), 8.15 (1H, dd, J=2.0, 8.8 Hz), 8.27 (1H, s), 8.71 (1H, s), 12.63 (1H, s); IR (KBr): 1635, 1677 (C═O) cm−1.
