Reaction Steps
A reactor is charged with 2-(methylamino)ethanol (134 g, 1.8 moles), 4-fluorobenzaldehyde (74.4 g, 0.6 mole), potassium carbonate (82.8 g, 0.6 mole) and dimethylsulfoxide (750 ml), and the mixture is heated at 95° C. for 72 hours. The product mixture is cooled and poured into three liters of ice water. The yellow solid that precipitates is filtered, washed with water, and dried in a vacuum oven, mp 72° C. The 4-[N-(2-hydroxyethyl)-N-methylamino]benzaldehyde product is recrystallized from water as needle-like crystals.
