Methyl 1-(5-bromopyrimidin-2-yl)-3-(methylthio)-1H-indole-6-carboxylate and 2-fluoro-5-methylyphenylboronic acid were submitted to a Suzuki reaction as described under 279b). The resulting coupling product was oxidized (m-CPBA) to the corresponding sulfoxide, transformed into its carboxylic acid (LiOH/THF/water) and then reacted with methyl 2-(methylamino)acetate hydrochloride (TBTU). Ester hydrolysis of the product methyl 2-(1-(5-(2-fluoro-5-methylphenyl)pyrimidin-2-yl)-N-methyl-3-(methylsulfinyl)-1H-indole-6-carboxamido)acetate, and subsequent reaction with HOBt ammonium salt provided the target compound as white solid.
