Participants

Reaction Steps

A solution of 2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-1-amine (1.50 g, 6.19 mmol) in 20 mL of isopropanol was treated with 2-furaldehyde (1.08 mL, 13.0 mmol) and 2 drops of concentrated HCl and heated to reflux under an atmosphere of nitrogen. After 48 h, the reaction was concentrated under reduced pressure to yield a brown oil. The oil was dissolved in 30 mL of CHCl3 and washed with 5% Na2CO3 solution, water and brine, dried over Na2SO4, filtered and concentrated under reduced pressure to yield N-(2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-1-yl)(furan-2-ylmethylene)amine (1.86 g) as a light brown solid.
