Reaction Steps

To a slurry of 2-chloro-4-cyanopyridine (10.00 g, 0.079 mol) and sodiumbicarbonate (19.92 g, 0.237 mol) in amine (0.174 mol) was added pyridine (35.0 mL) and the reaction was heated to 90° C. for 3 h. The reaction was then cooled to RT, diluted with the addition of CH2Cl2 (100 mL) and filtered. The solid was washed with EtOAc. Combined washes were concentrated in vacuo. A mixture of MeOH/hexanes was added and kept in the fridge for 12 h. The crystals that formed were filtered and washed with hexanes.
