Reaction Steps

A solution of 2,4,6-trichloropyridine (3.0 g, 16.4 mmol), 3-cyclopropyl-3-fluoroazetidine hydrogen chloride (2.49 g, 16.4 mmol) and DIPEA (7.09 ml, 41.0 mmol) in ethanol (40 ml) was heated under reflux for 1 h. Reaction mixture cooled to room temperature then concentrated to dryness in vacuo. Crude product purified by flash chromatography on silica (0 to 100% EtOAc:petrol) to give title compound as a white solid (1.56 g, 36%). 1H NMR (CDCl3) 0.52-0.48 (2H, m), 0.72-0.67 (2H, m), 1.42-1.31 (1H, m), 3.91 (2H, ddd), 4.05 (2H, ddd), 6.20 (2H, s). ES+ 261.30.
