Procedure
In a similar manner as described in Example 1 from 6-chloro-2-picoline (9.3 g, 73 mmol) and methyl nicotinate (10.0 g, 73 mmol), 2-(6-chloro-2-pyridinyl)-1-(3-pyridinyl)ethanone was obtained as a syrup. This syrup (10 g, 70 mmol) was treated with hydroxylamine hydrochloride (24.3 g, 350 mmol) followed by the addition of a sodium hydroxide solution (14 g, 350 mmol in 30 mL of water) as described in example 1 to give 2-(6-chloro-2-pyridinyl)-1-(3-pyridinyl)ethanone oxime (14.4 g, 80%) as a white solid. 1H NMR (CDCl3): δ 8.84 (d, 1H), 8.40 (dd, 1H), 8.00 (m, 1H), 7.50 (t, 1H), 7.2–7.4 (m, 3H), 4.26 (s, 2H); MS m/z 248 (M+1).
