Reaction Steps

To a solution of pentachloropyridine (30 g) in 2-propanol (300 ml) was added DIPEA (18 ml), DMAP (0.8 g) and (S)-(+)-2-amino-1-propanol (18 g), and the reaction mixture was heated under reflux for 18 h. After cooling, the reaction mixture was concentrated under reduced pressure. The residue was triturated with methanol and filtered to give the title compound as a white solid (18 g).
