Di-tert-butyl-iminodicarboxylate is an organic compound that can be described with the formula [(CH3)3COC(O)]2NH. It is a white solid that is soluble in organic solvents. The compound is used as a reagent for the preparation of primary amines from alkyl halides.[1] It was popularized as an alternative to the Gabriel synthesis for the same conversion. Amines can also be prepared from alcohols by dehydration using the Mitsunobu reaction.[2]

In the usual implementation the reagent is deprotonated to give the potassium salt, which is N-alkylated. The Boc protecting groups are subsequently removed under acidic conditions.
