Participants

Reaction Steps

A mixture of the product from step (v) (0.96 g) and thionyl chloride (10 mL) in DCM (20 mL) was heated under reflux for 6 h then evaporated under reduced pressure. The residue was dissolved in acetonitrile (20 mL) then N,N-dimethylethylenediamine (10 mL) added and the mixture heated under reflux for 24 h. The solvent was removed under reduced pressure and the residue purified by RPHPLC, yield 0.512 g.
