A solution of 2-[6-methoxy-4-(2-methyl-quinolin-3-yloxy)-quinolin-7-yloxy]-ethylamine (compound 354) (340 mg) in dichloromethane (1 ml) and N,N-dimethylformamide (0.5 ml) were added to 1,3-diboc-2-(trifluoromethylsulfonyl)guanidine (355 mg), and the mixture was stirred at room temperature for 4 hr. The solvent was removed from the reaction solution under the reduced pressure, water was added to the residue, and the mixture was extracted with chloroform. The chloroform layer was washed with water and was then dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by thin layer chromatography using chloroform-methanol to give N-{2-[6-methoxy-4-(2-methyl-quinolin-3-yloxy)-quinolin-7-yloxy]-ethyl}-N′,N″-diboc-guanidine (223 mg, yield 33%).
