Reaction Steps

A mixture of sodium hydride (6.09 g, 152.3 mmol) in 20 mL of dry dimethylformamide (DMF) was cooled to 0° C. and then 5-nitrovanillin (25 g, 126.8 mmol) in 41 mL of DMF was added dropwise. After 30 minutes, propyl iodide (25.87 g, 152.0 mmol) was added dropwise at 0° C. When the addition was completed, the reaction was maintained at room temperature for 2 hours and then stirred overnight at 70° C. Water was added, and the solution extracted with ethyl ether, washed with 10% NaOH, dried over MgSO4, filtered and then evaporated in vacuo to an oil (19 g, 62.7%).
