Versuchsvorschrift

A solution of 1.37 g (4.04 mmol) 1-methyl(S)-2-(4-amino-3-chloro-5-trifluoromethyl-benzyl)-succinate, 1.42 g (4.40 mmol) TBTU, 0.63 mL (4.50 mmol) triethylamine and 1.00 g (4.04 mmol) 6-hydroxy-3-piperidin-4-yl-3,4-dihydro-1H-quinazolin-2-one in 10 mL DMF was stirred for 3 h at RT. The reaction mixture was poured onto 300 mL saturated NaHCO3 solution, the precipitated substance was suction filtered, washed with 50 mL water and dried at 60° C. in the circulating air dryer.
