실험 절차

32.2 ml (0.23 mol) of trifluoroacetic acid were added dropwise to a solution of 22.3 ml (0.15 mol) of 2-(4-methoxyphenyl)ethylamine and 24.7 ml (0.23 mol) of pyridine in 125 ml of absolute THF cooled to 5° C., and the resulting solution was stirred at RT for 3 h. The reaction solution was then poured onto 750 ml of ice, and the deposited precipitate was filtered off with suction and dried at 40° C. in a high vacuum. 36.3 g of the title compound were obtained as a beige solid.
