실험 절차

To a solution of 2-Amino-3-(2-methoxy-pyrimidin-5-yl)-propionic acid methyl ester (125 mg) and diisopropylethylamine (0.3 mL) in methylene chloride (2 mL, 0° C.) was added N,N′-disuccinimidyl carbonate (155 mg). After 30 min, 3-piperidin-4-yl-3,4-dihydro-1H-quinazolin-2-one (120 mg) in methylene chloride (2 mL) was added via canula. The reaction was warmed to room temperature and stirred overnight. The reaction was concentrated and purified by prep HPLC to give 99 mg (36%). Mass spec.: 469.10 (MH)+.
