Reaction Steps

A mixture of 2-chloro-3-nitropyridine (20.0 g, 0.13 mole), 2-amino-1-phenylethanol (20.74 g, 0.15 mole), and triethylamine (17.5 ml, 0.13 mole) in 200 ml of absolute ethanol was heated to reflux for 11/2 hours. The reaction mixture was filtered and evaporated to dryness. The residue was partitioned between water and methylene chloride (2×). The methylene chloride layers were combined and extracted with water. The methylene chloride layers were dried, filtered, and evaporated to a solid (30.8 g, 94.5%). A 2.4-g sample was recrystallized from methanol and water to give a yellow solid, which was collected by filtration, washed with water, and dried under high vacuum overnight to give 1.8 g of the compound, mp 101°-103° C.
