反応手順

N-[2-(3-Amino-7-phenylquinolin-4-ylamino)-1,1-dimethylethyl]methanesulfonamide (2.20 g, 5.04 mmol) was treated with trimethyl orthobutyrate (0.90 mL, 5.5 mmol) according to the method described in Part G of Example 1. The chromatographic purification was carried out eluting with 92.5:7.5 dichloromethane:methanol to provide 1.8 g of N-[2-(7-phenyl-2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)-1,1-dimethylethyl]methanesulfonamide as a tan solid.
