Reaction Steps

A suspension of 11-{[tert-butyl(dimethyl)silyl]oxy}-9-(methylsulfonyl)-9,10,11,12-tetrahydro-8H-[1,4]diazepino[1′,2′:1,2]imidazo[4,5-c]quinolin-6-amine (1.0 g, 2.2 mmol) in anhydrous THF (30 mL) was cooled to −20° C., and tetrabutylammonium fluoride (2.383 mL of a 1 M solution in THF) was slowly added. The reaction was stirred overnight, and a precipitate formed. The cold reaction mixture was filtered, and the isolated precipitate was washed with THF and dried under high vacuum to provide 313.7 mg of 6-amino-9-(methylsulfonyl)-9,10,11,12-tetrahydro-8H-[1,4]diazepino[1′,2′:1,2]imidazo[4,5-c]quinolin-11-ol as white crystals, mp 282-283° C.
