A selective reagent for the deprotection of a tert-butyl-diphenylsilyl (TBDPS) ether in the presence of other protecting groups, using a solution of bromine in methanol under reflux is presented. By extension, this reagent has been introduced for the deprotection of TBDPS amines and esters and has also shown good selectivity in the removal of a TBDMS ether in the presence of a TBDPS one.
