실험 절차
A flask was charged with 1a (29.5 g) and acetic acid (44.3 g±5%), and then stirred. Bis-dimethylaminomethane (12.8 g±2%) was slowly added. The mixture was heated to 55±5° C. and maintained until reaction completion. The reaction product was evaluated by MS, HPLC and 1H NMR. 1H NMR (200 MHz, DMSO-d6) δ 11.7 (s, 1 H), 8.38 (d, J=9.0 Hz, 1 H), 7.61 (dd, J=9.0, 2.7 Hz, 1 H), 7.49 (m, 3 H), 7.21 (m, 3 H), 5.34 (s, 2 H), 3.97 (s, 3 H), 1.98 (s, 3 H); MS-(+)-ion M+1=368.12.
