Procedimiento

Under a nitrogen atmosphere phenyl isocyanate (1.00 mL, 9.25 mmol) was added dropwise to a chilled mixture of 4-[(2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-1-yl)methyl]piperidin-4-ol (3.00 g, 8.81 mmol) and dichloromethane (90 mL). The reaction mixture was allowed to warm to ambient temperature. After 2 hours the reaction mixture was concentrated under reduced pressure to provide an orange oil. This material was triturated with diethyl ether to provide 4.1 g of 4-[(2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-1-yl)methyl]-4-hydroxy-N-phenylpiperidine-1-carboxamide as a light orange solid.
