Triethylamine → hexadecyl N-(2-piperidinoethyl)carbamate

関与物質

反応手順

7.3 Grams of N-(2-aminoethyl)piperidine, 5.2 g of triethylamine and 100 ml of chloroform were charged in a flask equipped with a stirrer, a condenser and a calcium chloride drying tube and stirred with ice cooling. To the resulting solution was slowly added dropwise 15.8 g of hexadecyl chloroformate. After completion of the addition, the temperature of the solution was returned to room temperature, followed by refluxing with heating for 0.5 hour. The reaction mixture was cooled to room temperature, washed with water, dried over anhydrous magnesium sulfate and, then, concentrated under reduced pressure. The residue was recrystallized from methanol to obtain 16.3 g of the desired product. m.p. 48° C.
