Reaction Steps

16.2 g (104.2 mmol) of 4-acetyl-2-chloro-pyridine are stirred for 1 hour at 110° with 116 ml of dimethylformamide diethylacetal. After cooling to 0°, filtering and drying at 60° under HV, 3-dimethylamino-1-(2-chloro-4-pyridyl)-2-propen-1-one is obtained; 1 H-NMR (dimethyl sulfoxide): 2.98 (3H,s), 3.2 (3H,s), 5.9 (1H,d), 7.8 (3H,m), 8.5 (1H,d).
