Versuchsvorschrift

16 mg (0.033 mmol, 1 eq.) of 3-(4-chloro-3-formylphenyl)-1-(3,3-diphenylpropyl)-1-(2-morpholin-4-ylethyl)urea (obtained in Example 63) are dissolved in 0.7 mL of dry THF. Once the solution has been cooled to 0° C., 17 μL (0.049 mmol, 1.5 eq.) of magnesium methyl bromide in solution (3 M in diethyl ether) are added to the medium. After stirring for 20 min. at 0° C., the reaction is neutralised with a saturated ammonium chloride solution at 0° C. The aqueous phase is extracted with dichloromethane, the organic phases are washed with brine, dried over MgSO4, filtered and concentrated. The crude reaction product is subjected to chromatography over silica gel (eluent: 1/1 heptane/AcOEt). 11.4 mg of expected product are obtained (yield=67%).
