2-(4-Amino-1H-imidazo[4,5-c]quinolin-1-yl)ethanol (25 mg, 0.108 mmol) and N,N-dimethylformamide (1 mL) were combined. Phenol (12 mg, 0.130 mmol) and triphenylphosphine (34 mg, 0.130 mmol) were added and the resulting slurry was sonicated for about 1 minute. Diethyl azodicarboxylate (23 mg, 0.130 mmol) was added and the reaction mixture was shaken at ambient temperature for 24 hours. Analysis by LC-MS showed that a major amount of starting material remained. An additional equivalent each of phenol, triphenylphosphine and diethyl azodicarboxylate were added. The reaction mixture was sonicated for 30 minutes. After 1 hour analysis by LC-MS showed product. The solvent was removed and the residue was purified by semi-preparative HPLC using Method A: Mass Measurement: TM=304, NM[M+H]+1=305.
