Reaktionsschritte

70 mg (0.15 mmol, 1 eq.) of 3-(3-cyanophenyl)-1-(3,3-diphenylpropyl)-1-(2-morpholin-4-ylethyl)urea (obtained in Example 19) are dissolved in 0.5 mL of THF under argon. 142 μL (0.90 mmol, 6 eq.) of diethyldithiophosphate and 50 μL (0.01 mmol, 0.1 eq.) of water are added. The mixture is stirred for 27 hours at 40° C. Water is added to the medium and the aqueous phase is extracted with dichloromethane, washed twice with water then brine, dried over MgSO4, filtered and concentrated. The oil obtained is subjected to chromatography over silica gel (eluent: 97/3 dichloromethane/methanol) in order to obtain the expected product in the form of a yellow powder (55 mg, yield=73%).
