Acetyl chloride → 1-(3-Iodophenyl)-3-trimethylsilyoxy-2-aza-1,3-butadiene

Participants

Reaction Steps

In a manner similar to the method described in example 190b, 3-iodo-benzaldehyde (0.9 g, 3.88 mmol) (Aldrich) was used as the starting material in place of 2-[2-(tert-butyl-dimethyl-silanyloxy)-ethoxy]-5-iodo-benzaldehyde to react with 1,1,3,3,3-hexamethyldisilazane (0.62 g, 3.88 mmol), n-butyllithium (2.5 M, 1.6 mL, 3.88 mmol), trimethylsilyl chloride (0.42 g, 3.88 mmol), triethylamine (0.53 g, 5.28 mmol) and acetyl chloride (0.41 g, 5.28 mmol) to give 1-(3-iodophenyl)-3-trimethylsilyoxy-2-aza-1,3-butadiene as a yellow gum and used for the next step without further purification.
