Procedure

A stirred solution of 2-amino-3-(3-cyano-1H-indol-5-yl)-propionic acid methyl ester (25 mg, 0.11 mmol) in tetrahydrofuran (3 mL) at 0° C. was treated with carbonyl diimidazole (17.5 mg, 1.1 equiv.). The reaction was stirred for 5 min at 0° C., warmed to room temperature, stirred 10 min, and treated with 3-piperidin-4-yl-3,4-dihydro-1H-quinazolin-2-one (25 mg, 1.1 equiv.). The mixture was stirred at room temperature overnight. The solvent was evaporated and the residue purified by column chromatography to give 40 mg (75%) as a white powder. LC/MS: tR=1.37 min, 501.33 (MH)+.
