Reaction Conditions

Reaction Steps

To a mixture of 1-(2-(tert-butyldimethylsilyloxy)-2-methylpropyl)-4-iodo-1H-imidazole in DCM was added ethylmagnesium bromide at −78° C. The temperature of the mixture was allowed to warm up to about 10° C. slowly and cooled again. Trimethyltin chloride was added dropwise at −78° C. After the addition, the temperature was allowed to slowly warm up to room temperature. The reaction mixture was pouted into saturate NH4Cl solution, then extracted with DCM. The organic phase was washed with water twice, dried over anhydrous Na2SO4, and concentrated to give 1-(2-(tert-butyldimethylsilyloxy)-2-methylpropyl)-4-(trimethylstannyl)-1H-imidazole (Yield=74%).
