Participants

Reaction Steps

2-Ethoxymethyl-1-(3-isopropoxypropyl)-7-(morpholin-4-yl)-1H-imidazo[4,5-c]quinoline 5-oxide from Part B was dissolved in dichloromethane (4 mL). Ammonium hydroxide (2 mL) was added, followed by p-toluenesulfonyl chloride (0.074 g). The reaction was stirred for 24 hours. The layers were separated and the aqueous fraction was extracted with dichloromethane. The combined organic fractions were concentrated under reduced pressure to yield a yellow-brown oil. The oil was covered with diethyl ether and a precipitate formed. The solid was recovered by filtration and then dried to provide 0.085 g of 2-ethoxymethyl-1-(3-isopropoxypropyl)-7-(morpholin-4-yl)-1H-imidazo[4,5-c]quinolin-4-amine as a white powder, mp 161-162.5° C.
