Reaction Steps

Sodium hydroxide (12.00 g, 300 mmol) and acetophenone (24 g, 200 mmol) were dissolved in water (90 mL) and methanol (300 mL). 3-Bromobenzaldehyde (37 g, 200 mmol) dissolved in ethanol (50 mL) was added dropwise to the acetophenone solution. A slurry quickly formed, which was allowed to two additional hours. The slurry was filtered, was with water until the filtrate was neutral to pH paper, and dried at 80° C. for 12 hours. Light yellow crystals were obtained (43.4 g, 75.6% yield).
