Procedure

A solution of tert-butyl 2-{2-[2-(ethoxymethyl)-5-oxido-1H-imidazo[4,5-c]quinolin-1-yl]ethoxy}ethylcarbamate (16.06 g, 37.3 mmol) in 75 mL of CH2Cl2 was treated with 75 mL of concentrated NH4OH solution. The mixture was chilled in an ice water bath. To the rapidly stirred mixture was added solid p-toluenesulfonyl chloride (7.82 g, 41.0 mmol) over a 10 min period. The reaction mixture was then warmed to room temperature. After 30 min, the reaction was treated with 75 mL of CH2Cl2 and 75 mL of water and the layers were separated. The organic portion was then washed with 1% Na2CO3 solution (2×), water, brine, dried over Na2SO4, concentrated give 14.95 g of tert-butyl 2-{2-[4-amino-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]ethoxy}ethylcarbamate as a yellow solid.
