Procedure

To a solution of {[3-{[(tert-butoxycarbonyl)amino]methyl}-2-isobutyl-4-(4-methylphenyl)quinolin-6-yl]oxy}acetic acid (0.25 g, 0.52 mmol) in N,N-dimethylformamide (5 ml) was added di(N-succinimidyl) carbonate (0.42 g, 2.6 mmol), and the mixture was stirred at room temperature for 1 hr. To the reaction mixture were added methanesulfonamide (0.25 g, 2.6 mmol) and 1,8-diazabicyclo[5.4.0]-7-undecene (0.40 ml, 2.6 mmol), and the mixture was stirred at 100° C. for 5 hrs. The reaction mixture was cooled to room temperature and water was poured thereinto. The mixture was extracted with ethyl acetate and the extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated and the residue was crystallized from n-hexane-diisopropyl ether to give tert-butyl [(2-isobutyl-4-(4-methylphenyl)-6-{2-[(methylsulfonyl)amino]-2-oxoethoxy}quinolin-3-yl)methyl]carbamate (0.29 g, yield 98%) as pale-yellow crystals.
