Short Synthesis of Dopamine Agonist Rotigotine

A practical and short synthesis of FDA approved drug, Rotigotine is achieved in two steps from 5-methoxy-2-tetralone which in turn was synthesised using [4+2] cycloaddition of methoxy aryne and benzyloxy butadiene or from 4-methoxy indanone via ring expansion using trimethylsilyl diazomethane.
