Procedure

Intermediate 2,8-di(tert-butyl 3-phenylpropylcarbamate)benzothiophene was synthesized by Suzuki reaction of 2,8-dibromodibenzothiophene and tert-butyl 3-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propylcarbamate, which was obtained from tert-butyl 3-(3-bromophenyl)propylcarbamate. Compound 116 was obtained following similar de-protection reaction condition in route 2.
