実験手順

To a solution of N,N′-di-tert-butoxycarbonyl-7-(piperidin-4-ylmethoxy)-1,2,3,4-tetrahydroisoquinoline-2-carboxamidine (100 mg) in tetrahydrofuran (1.5 ml) were added pyridine (0.02 ml), 4-dimethylaminopyridine (12 mg) and α-toluenesulfonyl chloride (43 mg), and the mixture was stirred at room temperature for 12 hours and then at 50° C. for 6 hours. After completion of the reaction, the mixture was extracted with ethyl acetate and washed successively with water and saturated brine. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated. The obtained residue was purified by silica gel column chromatography (hexane:acetone=3:1) and dried under reduced pressure to give the title compound (48 mg).
