Participants

Reaction Steps

3-Methyl-1-phenacyl-quinolinium bromide: The title compound was prepared from 2-bromo-1-phenyl-ethanone (481 mg, 2.405 mmol), 3-methyl-quinoline (296 mg, 2.08 mmol) and acetonitrile (5 mL), similar to Example 1a, and yielded 640 mg (89%) as an off white solid: 1H NMR (CDCl3) 0.38 (d, J=1.8 Hz, 1H), 8.74 (s, 1H), 8.31 (m, 1H), 8.28 (m, 1H), 8.17 (dd, J=1.5, 8.4 Hz, 1H), 8.01 (m, 1H), 7.94–7.87 (m, 2H), 7.71 (m, 1H), 7.57 (t, J=7.8 Hz, 2H), 7.49 (s, 2H), 2.81 (s, 3H).
