Reaktionsschritte

β-Alanine (1 g, 11.2 mmol) was added to a solution of 9-phenoxyacridine (2.7 g, 10 mmol) in phenol (15 g). The suspension was stirred at 120° C. for 2 h. The solution was cooled to room temperature and poured into ether whereby the product precipitated as a yellow-green solid. It was triturated with hot ethanol, filtered and then washed with ethanol, giving crude 9-(2-carboxyethyl)aminoacridine. Yield 1.9 g (71%).
