Participants

Reaction Steps

Into a 500-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed 4-methoxybenzaldehyde (54.4 g, 400.00 mmol, 1.00 equiv), 2-aminopropan-1-ol (30 g, 400.00 mmol, 1.00 equiv), 4-methylbenzenesulfonic acid (3.84 g, 20.21 mmol, 0.05 equiv), toluene (300 mL). The resulting solution was heated to reflux for overnight in an oil bath. The resulting mixture was concentrated under vacuum. The resulting mixture was washed with 3×50 mL of hexane. The resulting solids were collected by filtration. This resulted in 63 g (82%) of (E)-2-(4-methoxybenzylideneamino)propan-1-ol as a white solid.
