Participants

Reaction Steps

4-{4-[4-(3-Sulfamoyl-propoxy)-indol-1-yl]-pyrimidin-2-ylamino}-cyclohexane-carboxylic acid ethyl ester (590 mg, 1.176 mmol) and LiOH.H2O (493.5 mg, 11.76 mmol) were combined in THF (2.5 mL), H2O (2.5 mL), and EtOH (2.0 mL) and allowed to stir overnight at RT. 10% HV1 solution was then added and the product precipitated. The organic solvents were removed in vacuo and the remaining suspension was filtered, washed with water and the yellow solid dried to yield 4-{4-[4-(3-sulfamoyl-propoxy)-indol-1-yl]-pyrimidin-2-ylamino}-cyclo-hexanecarboxylic acid (Compound 220, 550 mg, 99%).
