Abstract
The solid-phase synthesis of tertiary methylamines via the nucleophilic displacement of benzotriazole Mannich adducts with Grignard reagents using a hydroxylamine linker is described. The chemistry is exemplified by the synthesis of the MAO inhibitor α- methylpargyline. Also described is the synthesis of the analgesic Tramadol by an alternative one-pot solid-phase Mannich reaction.
