Versuchsvorschrift

A mixture of 5-((1-(3-(2-aminoethoxy)benzoyl)piperidin-4-yl)methyl)-2-((2S)-bicyclo[2.2.1]heptan-2-ylamino)-5-methylthiazol-4(5H)-one (100 mg, 0.207 mmol), K2CO3 (114 mg, 0.83 mmol), KI (Aldrich, 6.9 mg, 0.041 mmol), 1-chloro-2-(2-chloroethoxy)ethane (Aldrich, 38 mg, 0.27 mmol) in CH2Cl2 (3 mL) was heated at reflux for 10 d. Saturated NaHCO3 (50 mL) was added, and the crude product was extracted with CH2Cl2 (4×60 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Flash column chromatography (silica gel, CH2Cl2 with 0-4% MeOH) afforded the title compound as a colorless thin film (10 mg). MS (ESI, pos. ion) m/z: 555 (M+H).
