Reaction Steps
N-(3,4-Dimethoxyphenyl)-benzophenone hydrazone (1.0 equiv., 0.32 mmol, 105 mg), 2-hexanone (5 equiv., 1.58 mmol, 0.19 mL), and TsOH.H2O (10 equiv., 3.2 mmol, 609 mg) were dissolved in THF (10 mL) and heated to reflux for 67 hours. The reaction mixture was then cooled to room temperature, diluted with Et2O (5 mL), neutralized with a saturated NaHCO3 solution, and extracted with Et2O (3×10 mL). The organic extracts were then dried over K2CO3, filtered and concentrated under vacuum. Purification by flash column chromatography (20% EtOAc/Hex) gave the title product as a yellow oil (60 mg, 0.26 mmol, 80% yield).
