Reaction Steps

Using the three-step procedure of Example C5, ethyl 4,6-dichloronicotinate (20 g, 91 mmol) and isopropylamine (60% in water, 18 g, 182 mmol) were converted to 6-chloro-4-(isopropylamino)nicotinaldehyde (16 g, 81% yield). 1H NMR (400 MHz, DMSO-d6): δ 9.82 (s, 1 H), 8.43-8.39 (m, 2 H), 6.83 (s, 1 H), 3.84 (m, 1 H), 1.17 (d, J=6.4 Hz, 6 H).
