Procedure
Diethylamine (19 mL) was added to a solution of ((Z)-3-bromoprop-1-enyl)tributyl-stannane (Intermediate 3, 7.52 g) in THF (60 mL) and the mixture was stirred for 3 hours. The reaction mixture was evaporated to dryness and the residue was purified by chromatography on a silica column which had been pre-washed with 20% triethylamine in acetonitrile. The column was eluted with a mixture of ethyl acetate and pentane with a gradient of 0-10% to give N,N-diethyl-N—((Z)-1-tributylstannanylprop-1-en-3-yl)amine (4.75 g) as an orange oil.
