Abstract 3,6-disubstituted-2-nitrotoluenes were obtained in moderate yield by methylation of 2,5-disubstituted nitrobenzenes with dimethylsulfoniummethylide in DMSO-THF mixture.
A number of protected 7-hydroxyindoles was prepared by reaction of the protected 2-nitrophenols with vinylmagnesium bromide. Benzhydryl was shown to be the protecting group of choice, giving good yields of the indole and being readily removed for subsequent transformations of the 7-hydroxy function.
