Versuchsvorschrift

A modification of the general method described in Part C of Example 50 was followed using N-[2-(3-amino-7-benzyloxyquinolin-4-ylamino)-1,1-dimethylethyl]methanesulfonamide (12.6 g, 30.4 mmol) in lieu of tert-butyl {4-[3-amino-7-(benzyloxy)quinolin-4-ylamino]butyl}carbamate and ethoxyacetyl chloride (3.33 mL, 30.4 mmol) in lieu of methoxypropionyl chloride. The crude product was dissolved in dichloromethane (300 mL), and the resulting solution was washed with water (2×100 mL) and brine, dried over sodium sulfate, filtered, and concentrated under reduced pressure to provide a brown oil. The oil was purified by column chromatography on silica gel (eluting with 97.5:2.5 chloroform:methanol) to provide 12.4 g of N-[2-(7-benzyloxy-2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-1-yl)-1,1-dimethylethyl]methanesulfonamide as a beige foam.
