実験手順

A solution of 90 mg of ethyl((2,3-dihydro(1,4)dioxino(2,3-c)pyridin-7-ylmethyl)(1-(2-(7-methoxy-2-oxo-1,5-naphthyridin-1(2H)-yl)ethyl)piperidin-4-yl)amino)acetate in 0.2 mL of methanol and 1 mL of tetrahydrofuran, 0.2 mL of a 10% aqueous sodium hydroxide solution was added, and the mixture was stirred at room temperature for 2 hours. The reaction mixture was added with a 1 mol/L aqueous hydrochloric acid solution and neutralized, and the solvent was distilled off under reduced pressure. The resultant residue was purified by a resin; HP-20, made by Mitsubishi Chemical Corporation and an eluent of acetone to obtain 54 mg of ((2,3-dihydro(1,4)dioxino(2,3-c) pyridin-7-ylmethyl)(1-(2-(7-methoxy-2-oxo-1,5-naphthyridin-1(2H)-yl)ethyl)piperidin-4-yl)amino)acetic acid as a light yellow solid.
