Reaction Steps

A solution of 1-{4-amino-2-[(aminooxy)methyl]-1H-imidazo[4,5-c]quinolin-1-yl}-2-methylpropan-2-ol (800 mg, 2.65 mmol) in acetone (10 mL) and methanol (10 mL) was stirred for 20 hours at room temperature, then was concentrated under reduced pressure. The resulting yellow solid was purified by chromatography on a HORIZON HPFC system (silica gel, gradient elution with 5-15% methanol in chloroform) followed by crystallization from acetonitrile to yield 400 mg of acetone O-{[4-amino-1-(2-hydroxy-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-2-yl]methyl}oxime as pale yellow crystals, mp 212-216° C.
