Reaction Steps

In a similar manner as described in Example 1, from ethyl 4-bromobenzoate (12.8 mL, 78.3 mmol) and 6-chloro-2-picoline (4.3 mL, 39.2 mmol), 1-(4-bromophenyl)-2-(6-chloro-2-pyridinyl)ethanone (9.6 g, 82%) was obtained as a crystalline solid existing as a keto-enol tautomeric mixture. 1H NMR (CDCl3): for the keto tautomer δ 7.95 (d, 2H), 7.74–7.56 (m, 3H), 7.27 (m, 2H), 4.47 (s, 2H); MS m/z 310 (M+1).
