A. 2-(2-Bromophenyl)-1H-indole. An oven-dried 100-mL single-necked round-bottomed flask equipped with a Teflon-coated magnetic stir bar (oval, 25 mm × 15 mm) is charged with 2-bromoacetophenone (2.7 mL, 4.0 g, 20 mmol) (Note 1) and phenylhydrazine (2.4 mL, 2.6 g, 24 mmol) (Note 2) via syringe, and stirring is started. Phosphoric acid (10.0 mL) (Note 3) is added slowly over 1 min, and the mixture is stirred for 50 min (Note 4). NHNH2 H3C O Br H3PO4, PPA N H Br +
