Synthesis of SR9009 and SR9011

Compounds were synthesized by reductive amination of 5-nitro-2-thiophenecarboxaldehyde with 4-chlorobenzylamine and sodium triacetoxyborohydride yielded the secondary amine. A second reductive amination with 1-Boc-pyrrolidine-3-carboxaldehyde yielded the tertiary amine. This compound was treated with trifluoroacetic acid to remove the Boc-protecting group, and then reacted with either ethyl chloroformate (SR9009) or pentyl isocyanate (SR9011) to give the desired products.
