Procedure

To 10 mL of a tetrahydrofuran solution containing 600 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(7-methoxy-5-carboxy-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 420 mg of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride, 108 mg of O,N-dimethylhydroxylamine hydrochloride and 112 mg of N-methylmorpholine were added, and stirred at room temperature for 22 hours. Hydrochloric acid was added to the reaction mixture to make acidic, the organic layer was separated, washed sequentially with water, aqueous saturated sodium hydrogen carbonate solution and aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [Silica Gel; Fuji Silysia Chemical Ltd., Chromatorex-NH, eluent; ethyl acetate], to give 0.69 g of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(7-methoxy-5-((methoxy)(methyl)carbamoyl)-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate as a colorless oil.
