Reaction Steps

1-benzhydryl-3-(2-bromoethyl)-2-({[tert-butyl(dimethyl)silyl]oxy}methyl)-5-chloro-1H-indole (1 eq) was mixed with Methyl 4-mercaptobenzoate (2 eq) and KC2CO3 (1.9 eq) in DMF (0.09M). The resulting mixture was stirred at rt under N2 overnight. Water was then added, followed by regular work-up (eg. EtOAc extration, brine wash, etc) and column purification (1:6 EtOAc/Hexane as eluent) to give methyl 4-({2-[1-benzhydryl-2-({[tert-butyl(dimethyl)silyl]oxy}methyl)-5-chloro-1H-indol-3-yl]ethyl}sulfanyl)benzoate (yellow oil) in 81% yield.
