実験手順
A mixture of 4-[4-(4-bromoindol-1-yl)-pyrimidin-2-ylamino]-cyclohexane-carboxylic acid ethyl ester (5.8 g) and LiOH.H2O (1.65 g) in THF (100 mL), EtOH (40 mL) and H2O (30 mL) was stirred at RT overnight. The reaction mixture was then acidified with citric acid (7.54 g in 20 mL H2O), and stirred at RT for 1 h. The precipitate was filtered, washed with water, then Et2O, and dried to provide 4-[4-(4-bromoindol-1-yl)-pyrimidin-2-ylamino]-cyclo-hexanecarboxylic acid (5.27 g, 97%) as a white powder.
