Abstract

The present invention relates to new synthetic methods for preparing 2- methoxyisobutylisonitrile and metal isonitrile complexes, such as tetrakis(2- methoxyisobutylisonitrile)copper(I) tetrafluroroborate, which are used in the preparation of technetium (99mTc) Sestamibi, and novel intermediate compounds useful in such methods.
