Participants

Reaction Steps

1-(2-{(3,5-Bis-trifluoromethyl-benzyl)-[2-(ethoxycarbonyl-ethyl-amino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yl)-ethyl piperidine-4-carboxylate (70 mg) is dissolved in ethanol (4 ml), and thereto is added 1N-aqueous sodium hydroxide solution (1 ml) and the mixture is stirred at room temperature for 2 hours. To the reaction solution are added a 1N-hydrochloric acid and ethyl acetate, and the mixture is separated, and the organic layer is washed with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue is purified by silica gel column chromatography (chloroform:methanol=1:0→9:1) to give 1-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(ethoxycarbonyl-ethyl-amino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yl)-piperidine-4-carboxylic acid (44 mg). The resulting 1-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(ethoxycarbonyl-ethyl-amino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yl)-piperidine-4-carboxylic acid (44 mg) is dissolved in ethanol (1 ml), and thereto is added 1N-aqueous sodium hydroxide solution (44 μl), and then the mixture is concentrated under reduced pressure to give 1-(2-{(3,5-bis-trifluoromethyl-benzyl)-[2-(ethoxycarbonyl-ethyl-amino)-5-trifluoromethyl-benzyl]-amino}-pyrimidin-5-yl)-piperidine-4-carboxylic acid sodium salt (45 mg).
