Participants

Reaction Steps

To a stirred mixture of 10.2 g (0.036 mole) of 1-(2-acetoxy-1-methylethyl)-1H-imidazo[4,5-c]quinolin-5-oxide (prepared according to the method of Example 8) in 100 ml of dichloromethane was added in portions, 4.2 ml, 6.9 g (0.45 mole) of phosphorus oxychloride. After 4 hours the mixture was evaporated in vacuo. The residue was added to a saturated sodium bicarbonate solution, and that solution was extracted with chloroform. The chloroform layer was washed with both saturated sodium bicarbonate solution and water, dried over magnesium sulfate and evaporated in vacuo to yield light brown solid 1-(2-acetoxy-1-methylethyl)-4-chloro-1H-imidazo[4,5-c]quinoline.
