Procedure
To a solution of (±)-3-(7-methyl-1H-indazol-5-yl)-2-{[4-(2-oxo-1,4-dihydro-2H-quinazolin-3-yl)-piperidine-1-carbonyl]-amino}-propionic acid (50 mg, 0.105 mmol), EDCI (100 mg), and 4-dimethylaminopyridine (0.2 equiv.) in dimethylformamide was added aza-bicyclo[2.2.2]oct-3-yl alcohol (0.525 mmol, 5 equiv.). The mixture was stirred at room temperature overnight. The solvent was removed in vacuo and the residue was dissolved in ethyl acetate, washed with brine, dried over magnesium sulfate, and purified by preparative HPLC to yield the desired compound. LC/MS: tR=1.62 min, 586.41 (MH)+.
