Procedure

Ethyl 7-(4-{[N-(5-benzyloxy-1,2,3,4-tetrahydronaphthalen-1-ylcarbonyl)-N-(6-isopropylpyridin-3-yl)amino]methyl}pyrazol-1-yl)heptanoate (2.0 g) was dissolved in ethanol (100 mL), and 1 mol/L-aqueous sodium hydroxide solution (6.60 mL) was added. The mixture was stirred at room temperature for 1 hr. To the reaction mixture was added 1 mol/L-hydrochloric acid (6.60 mL), and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was purified by silica gel column chromatography to give 7-(4-{[N-(5-benzyloxy-1,2,3,4-tetrahydronaphthalen-1-ylcarbonyl)-N-(6-isopropylpyridin-3-yl)amino]methyl}pyrazol-1-yl)heptanoic acid (1.80 g). By the reaction and treatment of this compound in the same manner as in Example 139, 7-(4-{[N-(5-hydroxy-1,2,3,4-tetrahydronaphthalen-1-ylcarbonyl)-N-(6-isopropylpyridin-3-yl)amino]methyl}pyrazol-1-yl)heptanoic acid hydrochloride (0.84 g) was obtained.
