Reaction Steps

The 4-aminobenzil may be prepared according to the method of Augl et al, Annu. Conf., SPE, Reinf. Plastic/Compos. Div. Proc., 26th, 19D, 1 (1971). The 4-aminobenzil is rearranged to yield 4-aminobenzilic acid which is in turn esterfied to produce the ethyl ester. The ethyl ester of the 4-aminobenzilic acid is then reacted with quinuclidin-3-ol to give the expected 3-quinuclidinyl 4-aminobenzilate (4-amino-QNB). The purified 4-amino-QNB is then converted to the 4-triazeno-QNB according to the procedure reported by Tewson et al, J. Nucl. Med. 20, 671 (1979). The purified 4-triazeno-QNB is then reacted with iodide or a desired gamma-emitting radionuclide to produce the desired product.
