実験手順

Under a nitrogen atmosphere, a mixture of 1-tetradecanol (96.3 grams, 449 mmol), pyridine (40 milliliters), and dichloromethane (1000 milliliters) was heated to 30° C. 4-Nitrobenzoyl chloride (100 grams, 539 mmol) was added in portions over a twenty minute period. The reaction mixture was heated to reflux for sixteen hours. The reaction mixture was washed with water (2×500 milliliters). The organic layer was concentrated under reduced pressure to a yellow solid. 1000 milliliters of hexane was added and the mixture was heated to reflux. The mixture was cooled and filtered. The filtrate was concentrated to yield a yellow solid. The yellow solid was recrystallized twice from ethanol to obtain 77.0 grams of tetradecyl 4-nitrobenzoate as yellow crystals.
