Procedure

A solution of tert-butyl 2-(2-{[3-(propionylamino)quinolin-4-yl]amino}ethoxy)ethylcarbamate (15.00 g, 37.3 mmol) in 200 mL of EtOH was treated with triethylamine (13.0 mL, 93.2 mmol). The reaction was heated to reflux with stirring. After 3 days, the reaction was concentrated, triturated with ether and filtered to yield 13.78 g of tert-butyl 2-[2-(2-ethyl-1H-imidazo[4,5-c]quinolin-1-yl)ethoxy]ethylcarbamate as an off white solid.
