反応手順

Triphenylchloromethane (1.00 g, 3.58 mmol) (Wako Pure Chemical Industries, Ltd.) and ethanolamine hydrochloride (1.00 g, 10.3 mmol) (Wako Pure Chemical Industries, Ltd.) were dissolved in pyridine (4 mL), and the solution was stirred at room temperature for 3 days. Water (200 mL) was poured into the reaction solution, and the precipitates were suction-filtered. The solid matters were suspended in diethyl ether, and 3 (N) hydrochloric acid (Wako Pure Chemical Industries, Ltd.) was added thereto, followed by stirring at room temperature for 15 minutes. The insoluble matters were suction-filtered. The insoluble matters were dissolved in a mixed solution of ethyl acetate (Wako Pure Chemical Industries, Ltd.) and a saturated aqueous solution of sodium hydrogen carbonate (Wako Pure Chemical Industries, Ltd.), and the mixture was shaken, followed by the separation of the organic layer. The organic layer was dried with anhydrous sodium sulfate (Wako Pure Chemical Industries, Ltd.), and then suction-filtered and concentrated under reduced pressure, to thereby obtain the title compound (0.31 g, 28% yield).
