Benzoin (31.8 g, 0.15 mol) and urethane (42.79 g, 0.45 mol) were heated to reflux for 3.0 hours. The hot mixture was poured into water (150 mL). Acetone (150 mL) was added and heat was applied until the mixture dissolved. The solution was cooled and filtered, producing a white solid which was used in the next step without further purification.
