4-Picolyl chloride hydrochloride Use and Manufacturing

4-Chloromethylpyridine Hydrochloride (21); EMI35.0[0161] 4-Hydroxymethylpyridine (20) (54.4 g, 0.50 mol) was dissolved in acetonitrile 202 ml. The solution was added dropwise to a mixture of thionyl chloride (65.3 g, 0.55 mol) and acetonitrile (109 ml) under 50[deg.] C. The mixture was stirred at the same temperature for 1 hour, then cooled to room temperature to yield a slurry (quantitative) of the objective (21). [0162] <1>H-NMR (DMSO-TMS) [delta] ppm: 5.09 (s, 2H), 8.09 (d, J=6.6 Hz, 2H), 8.94 (d, J=6.6 Hz, 2H).(i)
