실험 절차
The title compound was prepared from 6-chloronicotinoyl chloride and 2,4-dimethoxyaniline as described in Example 1. The reaction mixture was filtered to remove the precipitate and the filtrate was evaporated. The resulting solid was purified by CH2Cl2/hexane recrystallization to give a light purple solid in a yield of 59%. 1H NMR (DMSO-d6): 9.77 (s, 1H), 8.93 (s, 1H), 8.35-8.31 (m, 1H), 7.68 (d, J=7.8, 1H), 7.46 (d, J=9.0, 1H), 6.67 (d, J=2.4, 1H), 6.57-6.53 (m, 1H), 3.80 (s, 3H), 3.78 (s, 3H).
