실험 절차

A solution of 3.0 g (8.83 mmol) 1-methyl (S)-2-(4-amino-3-chloro-5-trifluoromethyl-benzyl)-succinate and 3.05 g (9.5 mmol) TBTU, 1.28 g (9.47 mmol) HOBT in 1.7 mL (9.76 mmol) ethyldiisopropylamine and 1100 mL DMF was stirred for 1 h at RT. Then 2.2 g (9.51 mmol) 3-piperidin-4-yl-3,4-dihydro-1H-quinazolin-2-one were added and the reaction solution was stirred overnight at RT. The reaction mixture was evaporated down i.vac., the residue was taken up in DCM, washed with 10% citric acid solution and 15% K2CO3 solution and dried over Na2SO4. The desiccant was eliminated by filtering through activated charcoal; after elimination of the solvent the desired product was obtained.
