2-(Trichloroacetyl)pyrrole → 1-[5-(Trichloroacetyl)-1H-pyrrol-3-yl]propan-1-one

Participants

Reaction Steps

In a dry flask, 3-proprionyl chloride (1 equivalent) was combined with 2-trichloroacetyl pyrrole (1 equivalent) in a minimum amount of dichloromethane (DCM). To the resulting solution, at ambient temperature, was added aluminum trichloride (1 equivalent). After 2 hours, the reaction mixture was applied directly onto a silica gel column. Gradient elution with 10% ethyl acetate to 50% ethyl acetate in hexanes provided compound 3.
