実験手順
Solid magnesium turnings (9.5 g, 28 equiv.) under nitrogen atmosphere at room temperature were stirred vigorously with a magnetic stirring bar overnight. The magnesium was then covered with dry diethyl ether and to the suspension was added 1,2-dibromoethane (50 μL). A cold bath was then applied followed by dropwise addition of 1-chloromethyl-2-methoxy-benzene (18.18 g, 5 equiv. available from Aldrich Chemical Company) in diethyl ether (71 mL) which maintained the temperature at up to 15° C. The resulting black suspension was stirred at room temperature for 30 minutes and cooled down at −20° C. A solution of (4-Benzyl-morpholin-2-yl)-phenyl-methanone (4 g, 1 equiv.) in diethyl ether (50 mL) was then added dropwise via canula. The reaction mixture was left to warm to room temperature over two hours and then quenched by addition of aqueous saturated solution of NaHCO3 (50 mL). The aqueous solution was extracted with diethyl ether, the organic phase dried with MgSO4, evaporated in vacuo to give 7 g of a yellow amorphous solid. The compound was taken without further purification in the next step. FIA [M+H]+=404.
