実験手順
To a stirred solution of 3,4,5-trimethoxyacetophenone (213 mg, 1.01 mmol) in methanol (5 mL) was added 2N Ba(OH)2 solution (2 mL) after 5 minutes to the reaction mixture 2-(phenylamino)nicotinaldehyde (200 mg, 1.01 mmol) was added, stirred for 6 h at 30° C. The progress of the reaction was monitored by TLC for completion. After completion of the reaction, the reaction mixture was acidified with 2N HCl, the resulting precipitate was filtered, washed thoroughly with water and dried over anhydrous CaCl2. The resulting product was purified by by recrystallization from ethanol to afford compound 6a as a pale yellow solid (365 mg, 92% yield).; mp 125-128° C. 1H NMR (CDCl3): δ 8.26 (d, 1H, J=4.1 Hz), 8.01 (d, 2H, J=8.3 Hz), 7.95 (d, 1H, J=15.8 Hz), 7.81 (d, 1H, J=8.3 Hz), 7.55 (d, 1H, J=16.1 Hz), 7.48 (q, 2H), 7.01-7.09 (m, 3H), 6.83 (q, 1H), 6.62 (s, 1H), 3.91 (s, 3H) 3.84 (s, 6H); ESI MS: 391 (M+1)+.
