    摘要: Disclosed are processes for making 2,3 disubstituted indole compounds such as compounds of general formula I comprised of the steps of a) reacting a bromoindole compound (i) with a dialkoxyl C1-5 borane in the presence of a ligand, a palladium catalyst and a base to make a compound of general formula (ii); or alternatively reacting compound (i) with a trialkyl magnesiate reagent, followed by treatment with a borate; b) reacting the product of step a with a R2-Hal where R2-Hal is defined herein.
