Reaktionsschritte

A mixture of 26.2 mg (70 μmol) of 3-(4-bromo-benzyl)-1,3,8-triaza-spiro[4.5]decane-2,4-dione hydrochloride, 21.4 mg (70 μmol) of 3,3-diphenylpropyl bromide and 29 mg (210 μmol) of potassium carbonate in 1 mL of anhydrous DMF was heated overnight at 60° C. After cooling to room temperature, 0.5 mL of water was added and the solution was extracted with DCM (2×2 mL). The crude material was purified by semi-preparative HPLC (method A) yielding 12.8 mg (32.1%) of Compound 3 as a white solid.
