実験手順

In a three necked flask equipped with a dropping funnel, a thermometer and a reflux condenser, p-nitroaniline (138 g) was dissolved in a mixed solution of tetrahydrofuran (200 ml) with pyridine (140 ml) in a nitrogen atmosphere. To the solution, octadecanoyl chloride (333 g) was added through the dropping funnel over a time span of 20 minutes, while stirring the reaction mixture. After the completion of the dropwise addition, the reaction mixture was stirred for 2 hours. The resultant solid product was removed by filtering, and the filtrate was concentrated under reduced pressure, to produce crystals. The crystals were collected and recrystallized from ethanol. 4'-nitro-n-octadecaneanilide (364 g) was obtained at a yield of 90%.
